SD8530AS

PRIMARY SIDE REGULATOR WITH BUILT-IN HIGH VOLTAGE TRANSISTOR

Description Main feature Product specification classification Internal block diagram Technical documentation Relevant package outline drawing

SD8530AS is primary side regulator (PSR) with built-in high voltage transistor. It provides built-in cable drop compensation and peak current compensation. It adopts PFM technology and provides accurate constant voltage, constant current (CV/CC) control loop for high average efficiency and reliability.

Using SD8530AS for system design, few peripheral components are needed without requiring the Opto-coupler, Y capacitor, secondary control circuit and the loop compensation circuit which reduced the cost.

6W output power is recommended for SD8530AS in range of AC85~264V.

Main feature

Built-in high voltage transistor
Primary side control
Low start-up current
Leading edge blanking
Pulse-Frequency Modulation
Overvoltage protection
Undervoltage lockout
Short circuit protection
Over temperature protection
Open Loop Protection
Cable drop compensation
Peak current compensation
Cycle by cycle current limiting
