SY5002C Datasheet Flyback Controller

Manufacturer: Silergy

Overview: Applications Note: SY5002C Flyback Controller With Primary Side CV/CC Control For Adapters and Chargers.

General Description

SY5002C is a single stage Flyback controller targeting at Constant Current / Constant Voltage (CC/CV) applications.

Both current and voltage regulation are achieved by primary side control technology for low cost application.

To achieve higher efficiency and better EMI performance, SY5002C drives Flyback converters in the Quasi-Resonant mode and adaptive PWM/PFM control.

Key Features

  • Primary side CV/CC control eliminates the optocoupler.
  • Valley turn-on of the primary MOSFET to achieve low switching losses.
  • Internal CC/CV loop compensation.
  • The self-adaption compensation for better stability.
  • PWM/PFM control for higher average efficiency.
  • Fast dynamic load transient response.
  • Cable compensation for better load regulation.
  • Low start up current: 4µA Max.
  • Reliable protections for OVP, SCP, OTP.
