STR-W605x S 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 pensation function, avoiding subharmonic oscillation - Built-in Auto Standby function (Input Power, PIN < 30 m W 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 ponents. - 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 Continued on the next page… Description The STR-W605x S 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 ponents. The STR-W605x S 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 k Hz. 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 - munication equipment Package: 6-Pin fully molded TO-220F-6L (FM207) http://..net/ Not to scale Typical Application VAC VOU T STR-W6000S S/ OCP V CC GND FB/OLP BR 3 4 5 6...
