The STR-W6200D 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.

A PWM Off-Line Switching Regulator is a type of power supply or voltage regulator that operates as an offline switch-mode power supply (SMPS) and uses pulse-width modulation (PWM) to control the output voltage. These regulators are commonly used in a wide range of electronic devices and equipment to efficiently convert high-voltage AC (alternating current) power from the mains supply to low-voltage DC (direct current) power suitable for powering electronic circuits.


1. Current mode PWM control

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

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

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

5. Built-in Audible Noise Suppression function during Standby mode

6. Built-in startup circuit: reduces power consumption in standby operation, and eliminates external components

7. Bias-Assist function: improves startup operation, suppresses VCC pin voltage drop in operation, and allows use of smaller VCC capacitor

8. Built-in Leading Edge Blanking function
