KA3842AC Datasheet - Fairchild Semiconductor

KA3842AC SMPS Controller

The KA3842AC/KA3842AE are fixed PWM controllers for Off Line and DC to DC converter applications. The internal circuits include UVLO, low start up current, temperature compensated reference, high gain error amplifier, current sensing comparator, and high current totem pole output for driving a POWER.

KA3842AC Features

* Low start current 0.2mA (Typ.)

* Operating range up to 500kHz

* Cycle by cycle current limiting

* Under Voltage Lock Out (UVLO) with hysteresis

* Short shutdown delay time: Typ.100ns

* High current totem-pole output

* Output swing limiting: 2
