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.
