Description
Off-Line PWM Controllers with Integrated Power MOSFET
STR-W6000S Series
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.
