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 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 provides low start-up current...
