DP2525 is a low cost and high performance Primary Side Regulation (PSR) controller for offline small power converter applications which can provide very tight output voltage regulation (CV) and output current control (CC) ideal for charging applications. In CV mode, DP2525 adopts Multi Mode Control which uses the hybrid of AM (Amplitude Modulation) mode and (Frequency Modulation) FM mode to improve system efficiency and reliability.
