KA3842AC
SMPS Controller
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
DescriptionThe KA3842AC are fixed PWM controller for Off Line and
DC to DC converter applications. The internal circuits
include UVLO, low start up current circuit, temperature
compensated reference, high gain error amplifier, current
sensing comparator, and high current totem pole output for
driving a POWER MOSFET. Also KA3842AC provides low
start up current below 0.3mA and short shutdown delay
time typ. 100ns. The KA3842AC has UVLO threshold of
16V(on) and 10V(off). The KA3842AC can operate within
100% duty cycle.
