HI-SINCERITY Spec. No. : IC200916 Issued Date : 2009.09.12 Revised Date : Page No. : 1/5 MICROELECTRONICS CORP. H960 High Efficiency Current Mode PWM Controller Description H960 is a high performance PWM controller IC specially designed for low power AC/DC application. Implemented with Avantics patented proprietary technology, H960 can provide a “No Y-Cap” AC/DC solution with distinguished Package : DIP-8 Package Code : P advantages in low standby power, high efficiency and better OVP performance Features Over-load and saturation protection with patent design technology, which can prevent over-load, switching z transformer saturation, output short circuit and other faults in time. Built-in bipolar power transistor for switching, achieves start-up uses its magnification function as well, z which can reduce the power of the start-up resistance to less than 1/10. z Built-in slope compensation circuit; over temperature protection circuit; slope current driving circuit. z 5.5W of wide voltage output; 8W of 220Vac output; less than 0.25W when there is no load. Application z Adaptor, Charger z LCD standby power z Home appliance Power z Low Power AC/DC switch mode power supply( up to 8W) 4 3 2 H960 1 5 6 8 7 Pin Descriptions Pin No. Symbol Description 1 OB Base of power transistor; Start-up current control 2 CT Oscillator Input C 3 GND 4 FB 5 VCC 6 OE Emitter of power transistor; Start-up current input 7 OC Collector of power transistor 8 OC Collector of power transistor Built-in test pin VR 2.5V reference voltage Built-in test pin IS Current of power transistor Ground Feedback input Power supply HSMC Product Specification HI-SINCERITY MICROELECTRONICS CORP.
