Description:
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
Built-in Slope Compensation function, avoiding subharmonic oscillation
Built-in Auto Standby function (Input Power, PIN < 30 mW at no load)
Normal operation: PWM mode
Light load operation: Standby mode (burst oscillation)
Built-in Audible Noise Suppression function during Standby mode
Built-in Startup Circuit, reducing power consumption in standby operation, and eliminating external components.
Bias-Assist function, improving startup operation,suppressing VCC voltage drop in operation, and allowing use of smaller VCC capacitor
Built-in Leading Edge Blanking function.

Applications:
For switching power supplies used in:
White goods
Consumer electronics
Office automation
Industrial equipment
Communication equipment
