[ Alternative : STR3A453D]
STR-W6052S
Package：TO220F-6L
The STR-W6000S series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC.
Including an auto standby function in the controller, the product achieves the low standby power 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.
