Package : TO220F-6L

RoHS : YES

The STR-W6200D series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controll IC in one package.
Including a startup circuit and a standby function in the controller, the product achieves low power consumption, low standby power, and high cost-effectiveness in power supply systems, while reducing external components.
