Objective [Heading]	rr_ObjectiveHeading	INVESTMENT OBJECTIVE
Objective, Primary [Text Block]	rr_ObjectivePrimaryTextBlock	The Fund seeks to provide current income as well as preservation of capital.
Expense [Heading]	rr_ExpenseHeading	FUND FEES AND EXPENSES
Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	The following table describes the fees and expenses that you may pay if you buy and hold Fund shares. You may qualify for sales charge discounts of the Fund if you and your family invest, or agree to invest in the future, at least $50,000 in PNC Funds. More information about these and other discounts is available from your financial intermediary and in the "Sales Charges" section of the Fund's prospectus on page 65 and in the "Additional Purchase and Redemption Information" section of the Fund's statement of additional information.
Shareholder Fees Caption [Text]	rr_ShareholderFeesCaption	Shareholder Fees (fees paid directly from your investment)
Operating Expenses Caption [Text]	rr_OperatingExpensesCaption	Annual Fund Operating Expenses (expenses that you pay each year as a percentage of the value of your investment)
Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	PORTFOLIO TURNOVER
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 29% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	Example
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in Class A or Class C Shares of the Fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year, and that the Fund's operating expenses remain the same, except that the contractual limitation on Distribution (12b-1) Fees for Class A Shares is reflected only in the one year period below. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	PRINCIPAL INVESTMENT STRATEGIES
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests in a diversified portfolio of mortgage-related securities. The dollar-weighted average maturity of the Fund's portfolio is normally expected to range from three to ten years, but may vary outside that range from time to time, including due to market conditions. Under normal circumstances, the Fund invests at least 80% of its net assets plus any borrowings for investment purposes in mortgage-related securities issued or guaranteed by agencies, authorities, instrumentalities or sponsored enterprises of the U.S. government. The Fund will provide shareholders with at least 60 days' written notice before changing this 80% policy. The Fund may invest up to 20% of its assets in other types of investments including securities issued by non-governmental issuers, such as mortgage -related debt securities, asset-backed debt securities, commercial paper and preferred stock. In buying and selling securities for the Fund, PNC Capital Advisors, LLC (the "Adviser") considers a number of factors, including yield to maturity, maturity, quality and the outlook for particular issuers and market sectors. The Fund also utilizes an active trading approach. The Adviser may choose to sell a holding when, for example, it no longer offers attractive growth prospects or to take advantage of a better investment opportunity.
Risk [Heading]	rr_RiskHeading	PRINCIPAL RISKS
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Active Trading Risk. To the extent that the Fund buys and sells securities actively, it could have higher expenses (which reduce return for shareholders) and higher taxable distributions. Credit/Counterparty Risk. The values of debt securities or other instruments may be affected by the ability of issuers or the respective counterparties to make principal and interest payments or otherwise meet their obligations to the Fund. If an issuer cannot or will not meet its payment obligations or if its credit rating is lowered or its financial strength deteriorates, the values of its debt securities or other instruments may fall. Obligations issued by U.S. government agencies, authorities, instrumentalities or sponsored enterprises, such as the Government National Mortgage Association, are backed by the full faith and credit of the U.S. Treasury, while obligations issued by others, such as the Federal National Mortgage Association, the Federal Home Loan Mortgage Corporation and Federal Home Loan Banks, are backed solely by the ability of the entity to borrow from the U.S. Treasury or by the entity's own resources. Foreign (Non-U.S.) Investment Risk. Investments in securities of foreign companies or governments can be more volatile than investments in U.S. companies or governments. Diplomatic, political, or economic developments, including nationalization or expropriation, could affect investments in foreign countries. Foreign securities markets generally have less trading volume and less liquidity than U.S. markets. In addition, the values of securities denominated in foreign currencies, and of dividends from such securities, can change significantly when foreign currencies strengthen or weaken relative to the U.S. dollar. Foreign companies or governments generally are not subject to uniform accounting, auditing, and financial reporting standards comparable to those applicable to domestic U.S. companies or governments. Transaction costs are generally higher than those in the U.S. and expenses for custodial arrangements of foreign securities may be somewhat greater than typical expenses for custodial arrangements of similar U.S. securities. Government Securities Risk. Investments in certain U.S. government securities may not be supported by the full faith and credit of the U.S. government. Accordingly, no assurance can be given that the U.S. government will provide financial support to U.S. government agencies, instrumentalities or sponsored enterprises if it is not obligated to do so by law. The maximum potential liability of the issuers of some U.S. government securities held by the Fund may greatly exceed their current resources, and it is possible that these issuers will not have the funds to meet their payment obligations in the future. In such a case, the Fund would have to look principally to the agency, instrumentality or sponsored enterprise issuing or guaranteeing the security for ultimate repayment, and the Fund may not be able to assert a claim against the U.S. government itself in the event the agency, instrumentality or sponsored enterprise does not meet its commitment. Concerns about the capacity of the U.S. government to meet its obligations may raise the interest rates payable on its securities, negatively impacting the price of such securities already held by the Fund. Interest Rate Risk. The value of a debt security typically changes in the opposite direction from a change in interest rates. When interest rates go up, the value of a debt security typically goes down. When interest rates go down, the value of a debt security typically goes up. Generally, the longer the maturity or duration of a debt security (or a portfolio of such securities), the more the value of that security (or portfolio of securities) will change as a result of changes in interest rates. Market Risk. Market risk is the risk that securities prices will fall over short or extended periods of time. Historically, the stock markets have moved in cycles, and the value of the Fund's securities may fluctuate from day to day. Individual companies may report poor results or be negatively affected by industry and/or economic trends and developments. The prices of securities issued by such companies may decline in response. Prepayment/Extension Risk. Certain debt obligations, such as callable bonds, may be prepaid. Additionally, the loans collateralizing certain mortgage- and asset-backed securities may be prepaid, affecting the value of the mortgage or asset-backed securities to which they relate. The level of interest rates and other factors affect the frequency of such prepayments. In periods of rising interest rates, prepayment rates tend to decrease, which lengthens the average life of callable bonds or mortgage- and asset-backed securities. The market values of securities with longer average lives (longer maturities) tend to be subject to greater interest rate risk and their values are more volatile as a result. In periods of falling interest rates, prepayment rates tend to increase, shortening the average life of a pool of mortgage-backed securities. This leads to the risk that the Fund may lose any potential price appreciation above the bond's call price and have to reinvest the proceeds from prepayments at lower interest rates because prepayments often occur after interest rates have decreased or when interest rates are falling. All investments are subject to inherent risks, and an investment in the Fund is no exception. Your investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Accordingly, you may lose money by investing in the Fund.

[1] A sales charge is not charged on purchases of Class A shares in the amount of $1,000,000 or more. However, a contingent deferred sales charge of 0.50% is charged if you redeem Class A Shares purchased in the amount of $1,000,000 or more within 18 months. In addition, a contingent deferred sales charge of 1.00% is charged if you redeem Class C Shares prior to 18 months from the date of purchase.

[2] The Fund may reimburse expenses up to a maximum of 0.10% under the Fund's distribution plan for Class A Shares. The Board of Trustees has approved a contractual commitment whereby such reimbursements will be no more than the Distribution (12b-1) Fees stated in the table above for the Fund. This commitment continues through September 27, 2013, at which time the Board will determine whether to renew, revise or discontinue it.

[3] After-tax returns are shown for Class A Shares only. After-tax returns for Class C Shares will differ. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes.
