1 / 21 page  Primary Side Regulation Off-Line PWM Controllers with Integrated Power MOSFET STR5A100D Series STR5A100D-DS Rev.1.2 SANKEN ELECTRIC CO.,LTD. 1 Dec. 25, 2013 General Descriptions The STR5A100D series is power IC with primary side regulation for switching power supplies, incorporating a sense MOSFET and a current mode PWM controller IC. Employing the Primary Side Regulation, the product achieves power supply systems with few external components. Including a startup circuit and a standby function in the controller, the product achieves the low standby power by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load conditions. The rich set of protection features helps to realize low component counts, and high performance-to-cost power supply. Features Primary Side Regulation Constant Voltage (CV), Constant Current (CC) Control Auto Standby Function No Load Power Consumption < 30mW Operation Mode ・Normal Operation -------------------------- PWM Mode ・Light Load Operation ----------------------Green-Mode ・Standby------------------------- Burst Oscillation Mode Build-in Startup Circuit (reducing power consumption at standby operation, shortening the startup time) Current Mode Type PWM Control Random Switching Function Leading Edge Blanking Function Soft Start Function (reducing the stress of power MOSFET and secondary side rectifier diode at startup) Protections Overcurrent Protection (OCP) ------------Pulse-by-Pulse Overvoltage Protection (OVP) ------------- Auto-Restart Thermal Shutdown Protection (TSD) ----- Auto-Restart Typical Application Circuit VAC C1 R1 D1 T1 D P C5 C4 C3 R6 R3 R5 D2 BR1 COMP S/GND VCC FB D/ST S/GND S/GND 8 7 6 5 STR5A100D U1 1 2 4 R2 L1 C2 R4 D50 S1 VOUT GND C52 C51 R51 C6 R7 R52 Package DIP8 Not to scale Lineup Electrical Characteristics VD/ST(max.) = 730 V fOSC(AVG)(typ.) = 65 kHz Products RDS(ON) (max.)
