KA3882C
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 KA3882C/KA3883C is a fixed PWM controller for Off
Line and DC to DC converter applications. The internal
circuits include an 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
KA3882C/KA3883C provides low start-up current below
0.3mA and short shutdown delay time typ. 100ns. The
KA3882C has the UVLO threshold of 16V (on) and
10V(off). The KA3883C is 8.4V(on) and 7.6V(off). The
KA3882C and KA3883C can operate within 100% duty
cycle.
