KA3882C Datasheet Smps Controller

Manufacturer: Fairchild (now onsemi)

Overview: .fairchildsemi. KA3882C/KA3883C SMPS Controller.

General 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 time typ.

Key Features

  • Low Start Current 0.2mA (Typ) Operating Range Up To 500kHz Cycle by Cycle Current Limiting Under Voltage Lock Out With Hysteresis Short Shutdown Delay Time: Typ.100ns High Current Totem-Pole Output Output Swing Limiting: 22V.
