SY50131 Overview
SY50131 is a single stage Flyback controller targeting at Constant Current/Constant Voltage (CC/CV) applications. It integrates a 600V MOSFET to decrease physical volume. Both the output current and voltage are sensed by primary side signal process.
SY50131 Key Features
- Very tight PSR CC/CV regulation over entire operating range
- QR-mode operation for high efficiency
- PWM/PFM control for higher average efficiency
- Internal CC/CV loop pensation
- The self-adaption pensation for better stability
- Fast dynamic load transient response
- Cable pensation for better load regulation
- Low start up current: 4µA Max
- Reliable protections for OVP, SCP, OTP
- Reliable protections for safety requirement
