KA3882C - Fairchild

KA3882C SMPS Controller

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 compensated reference, a high gain error amplifier, a current sensing comparator, and the high current totem-pole output for driving a POWER MOSFET. Also the KA3882C/KA3883C provi.
