STR W6053S Sanken Off-Line PWM Controllers with Integrated Power MOSFET

General Descriptions

The STR-W6000S series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC. The low standby power is accomplished by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load conditions. The product achieves high cost-performance power supply systems with few external components.


 Current Mode Type PWM Control
