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
advantages in low standby power, high efficiency and better OVP performance
Package : DIP-8
Package Code : P
Features
z Over-load and saturation protection with patent design technology, which can prevent over-load, switching
transformer saturation, output short circuit and other faults in time.
z Built-in bipolar power transistor for switching, achieves start-up uses its magnification function as well,
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)
