6215 is a high performance Quasi Resonant (QR) Primary Side Regulation (PSR) PWM power switch with high precision CV/CC control ideal for
Built-in 800V Power BJT Quasi-Resonant Primary Side Regulation (QR-PSR) Control with High Efficiency Multi-Mode PSR Control Fast Dynamic Response Built-in Dynamic Base Drive Audio Noise Free Operation ±4% CC and CV Regulation Low Standby Power <70mW Programmable Cable Drop Compensation (CDC) in CV Mode Built-in AC Line & Load CC Compensation Build in Protections: Short Load Protection (SLP) Cycle-by-Cycle Current Limiting (OCP) Leading Edge Blanking (LEB) On-Chip Thermal Shutdown (OTP) VDD OVP & UVP & Clamp Available in SOP-7 Package
charger applications. In CV mode, 6215 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 can provide excellent CV performance
