Description
The KA3882E/KA3883E is a fixed PWM controller for Off-Line and DC to DC converter applications. The internal circuits include a 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 KA3882E/KA3883E provides low start-up current below 0.3mA and short shutdown delay time typ. 100ns. The KA3882E has UVLO threshold of 16V(on) and 10V(off). The KA3883E is 8.4V(on) and 7.6V(off). The KA3882E and
KA3883E can operate within 100 duty cycle.
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
