STRA60xxM Overview
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 ponents. The STR-A60xxM internal MOSFET has a V DSS of 650 V(min) or 800 V(min), and...
STRA60xxM Key Features
- 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 pensation function, avoiding subharmonic oscillation
- Built-in Auto Standby function (Input Power, PIN < 25 mW at no load) ▫ Normal operation: PWM mode ▫ Light load operation
- 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 smalle
STRA60xxM Applications
- 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
