SDH8592AS
HIGH PRECISION CC/CV PRIMARY SIDE POWER SWITCH CONTROLLER WITH INTEGRATED MOSFET

    SDH8592AS is a high performance off-line PSR power switch which operates in PFM to achieve high performance and high efficiency. It integrates a  MOSFET and high voltage startup to decrease physical volume. Both the output current and voltage are sensed by primary side signal process. 

    SDH8592AS removes the need for secondary feedback circuitry while achieving excellent line and load regulation. It also eliminates the need for loop compensation while maintaining stability over all operation conditions.

Main feature

  • Primary-side Feedback Eliminates Opto-isolators 

  • High Precision Constant Voltage and Current Regulation at Universal AC Input

  • Ultra Low Start-up Current 

  • Programmable CV and CC Regulation

  • Programmable Cable Drop Compensation

  • Integrated 650V MOSFET

  • Integrated High Voltage Startup 

  • Less Than 75mW Standby Power

  • Built-in Line Voltage and Primary Winding Inductance Compensation

  • Built in Leading Edge Blanking(LEB)

  • No External Compensation Required

  • On-chip OTP

  • VCC Over Voltage Protection

  • Output Over Voltage Protection

  • VCC Under Voltage Lockout with Hysteresis(UVLO)

  • Cycle-by-Cycle Current Limiting

  • Output Short Circuit Protection
