STR-A60xxM Current Mode Control PWM Regulator IC For Switching Power Supplies
Features and Benefits
▪ Small DIP8 package with 8 to 24 W power output 230 VAC ▪ Current Mode PWM control with 67 kHz switching frequency ▪ 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 < 25 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

Description
The STR-A60xxM 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-A60xxM internal MOSFET has a V DSS of 650 V(min) or 800 V(min), and an RDS(on) of 1.9 to 19.2 Ω with a frequency of 67 kHz. Power output is rated at 8 to 24 W at 230 VAC input and 5 to 20 W at wide input range (85 to 265 VAC). The device is provided in an industry-standard DIP-8 package, with pin 6 removed for increased isolation.
Applications:
For switching power supplies used in: • Battery chargers for cell phones, digital cameras, video cameras, shavers, emergency lights • Stand-by power for LCD TVs, desktop PCs, LB Printers, audio equipment • Small switched-mode power supplies for inkjet printers, DVD/CD players, set-top boxes • Auxiliary power supplies for A/C, refrigerators, washers, dish washers, and other white goods
