KA3883E
SMPS Controller
Features Low Start Current 0.2mA (typ) Operating Range Up To 500KHz Cycle by Cycle Current Limiting Under V oltage Lock Out With Hysteresis Short Shutdown Delay Time: typ.100ns High Current Totem-pole Output Output Swing Limiting: 22V
DescriptionThe KA3882E/KA3883E are fixed PWM controller for Off-
Line and DC to DC converter applications. The internal cir-
cuits include UVLO, low start up current circuit, tempera-
ture compensated reference, high gain error amplifier,
current sensing comparator, and high current totem-pole out-
put for driving a POWER MOSFET. Also KA3882E/
KA3883E provide 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.
