STRA60xxM - Allegro MicroSystems

STRA60xxM Current Mode Control PWM Regulator

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 .

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 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 operati.
