STR-W6253D datasheet


The STR-W6253D series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller 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.


1. TO-220 fully-molded package with 6 pins

2. Current mode PWM control

3. PWM and frequency modulation functions: reduces EMI noise, simplifies EMI filters, and cuts
cost by external part reduction

4. Built-in Slope Compensation circuit: avoids subharmonic oscillation

5. Automatic Standby Mode function (Input Power < 40 mW at no load)
