Data Sheet
Quasi-Resonant Primary Side Regulation CV/CC Power Switch
- Features
U6215 is a high performance Quasi Resonant (QR) Primary Side Regulation (PSR) PWM power switch with high precision CV/CC control ideal for charger applications.
In CV mode, U6215 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 pensation. The IC can achieve fast dynamic response. The built-in Cable Drop pensation (CDC) function can provide excellent CV performance.
U6215 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), On-Chip Thermal Shutdown, VDD Clamping, etc .
