STR-W605xS Current Mode Control PWM Regulator IC For Switching Power Supplies
Features and Benefits
▪ 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

Description
The 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 Ω (max) to 3.95 Ω (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.

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

Package: 6-Pin ful
