GENERAL DESCRIPTION
DP2525x is a high performance Quasi Resonant (QR) Primary Side Regulation (PSR) PWM powerswitch with high precision CV/CC control ideal for charger applications.In CV mode,
DP2525x adopts Multi Mode QR Control which uses the hybrid of AM (Amplitude Modulation) mode and (Frequency Modulation) FM mode to improve system efficiency and reliability. In CC mode, the IC uses PFM control with line and load CC compensation. The IC can achieve fast dynamic response. The built-in Cable Drop Compensation (CDC) function canprovide
excellent CV performance.
DP2525x integrates functions and protections of Under Voltage Lockout (UVLO), VDD over Voltage Protection (VDD OVP), Cycle-by-cycle Current Limiting (OCP), Short Load Protection (SLP), OnChip Thermal Shutdown, VDD Clamping, etc.
