KA3882C Description
The KA3882C/KA3883C is a fixed PWM controller for Off Line and DC to DC converter applications. The internal circuits include an UVLO, a low start up current circuit, a temperature pensated reference, a high gain error amplifier, a current sensing parator, and the high current totem-pole output for driving a POWER MOSFET. Also the KA3882C/KA3883C provides low start-up current below 0.3mA and short shutdown delay...
