KA3842AC/KA3842AE

SMPS Controller

Features

Description

Low start current 0.2mA (Typ.)

Operating range up to 500kHz

Cycle by cycle current limiting

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, tem-

perature compensated reference, high gain error ampli-

fier, current sensing comparator, and high current totem

pole output for driving a POWER MOSFET. Also

KA3842AC/KA3842AE provides low start up current

below 0.3mA and short shutdown delay time, typically

100ns. The KA3842AC/KA3842AE has a UVLO thresh-

old of 16V(on) and 10V(off). The KA3842AC/KA3842AE

can operate within a 100% duty cycle.

Under Voltage Lock Out (UVLO) with hysteresis

Short shutdown delay time: Typ.100ns

High current totem-pole output

Output swing limiting: 22V
