This is Off-Line PWM Controllers with Integrated Power MOSFET.

The STR-W6051S, STRW6051S 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.
