The STR-W605x/STR-W605xS series are power ICs for switching power supplies, incorporating a power MOSFET and a current mode PWM controller IC. Including a startup circuit and a standby function in the controller, the product achieves low power consumption, low standby power, and high cost-effectiveness power supply systems with few external components.The STR-W605xS internal MOSFET has a VDSS of 650 V (min),and an RDS(on) of 1.9 (max) to 3.95 (max) with a frequency of 67 kHz. Power output is rated at 45 to 90 W at 230 VAC input and 30 to 60 W at wide input range (85 to 265 VAC).The device is provided in an industry-standard TO-220 package,with heatsink mounting flange and pin 2 removed for increased supply isolation.
Features:
TO-220F power package with 30 to 90 W power output
Current Mode PWM control
Built-in Random Switching function, reducing EMI noise,and simplifying EMI filters, and therefore reducing cost
