SY50133 Datasheet Flyback Regulator

Manufacturer: Silergy

Overview: 昱灿电子 .szyucan. Applications Note: SY50133 Flyback Regulator With Primary Side CV/CC Control For Adapters and Chargers Preliminary Specification.

General Description

SY50133 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.

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 compensation.
  • The self-adaption compensation for better stability.
  • Fast dynamic load transient response.
  • Cable compensation for better load regulation.
  • Low start up current: 4µA Max.
  • Reliable protections for OVP, SCP, OTP.
  • Reliable protection.
