Description
STR-W6000S Series PWM Off-Line Switching Regulator ICs .
The STR-W6051S, STR-W6052S, and STR-W6053S are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller.
Features
* ▪ Current mode PWM control ▪ Brown-In and Brown-Out function: auto-restart, prevents
excess input current and heat rise at low input voltage ▪ Auto Standby function: improves efficiency by Burst
mode operation in light load ▫ Normal load operation: PWM mode ▫ Light load operation: Burst mode ▪ No lo
Applications
* Switching power supplies for electronic devices such as:
* Home appliances
* Digital appliances
* Office automation (OA) equipment
* Industrial apparatus
* Communication facilities
