Introduction

AI Translation

SY5018B is a single stage Flyback and PFC controller targeting at Constant Voltage (CV) applications. Primary side control is applied to reduce the feedback circuit cost. It drives the Flyback converter in the Quasi-Resonant mode for high efficiency and achieves high power factor by constant on time control scheme. Adaptive PWM/PFM control is adopted for highest average efficiency.

Features

AI Translation
  • Primary side CV control eliminates the opto-coupler.
  • Valley turn-on of the primary MOSFET to achieve low switching losses
  • Internal high current MOSFET driver: 0.1A sourcing and 0.5A sinking
  • Power factor >0.90 with single-stage conversion
  • Maximum switching frequency limitation 100kHz
  • Compact package: SO8
  • Output current limit, about 1.2 times the rated current

Applications

AI Translation
  • AC/DC adapters
  • Battery Chargers
  • LED Lighting
