Off-Line PWM Controllers with Integrated Power MOSFET STR-A6000 Series General Descriptions The STR-A6000 series are power ICs for switching power supplies, incorporating a MOSFET and a current mode PWM controller IC. The low standby power is accomplished by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load conditions. The product achieves high cost-performance power supply systems with few external components. Features Current Mo

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 kH- 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
