KA3884 General Description
The KA3882/3/4/5 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 totempole output for driving a POWER MOSFET. Also KA 3882/3/4/5 provide low start up current below 0.3mA and short shutdown delay time typ. 100ns.
The KA3882 and KA3884 have UVLO threshold of 1 6V(on) and 10V(off).
The KA3883 and KA3885 are 8.4V(on) and 7.6V(off).
The KA3882 and KA3883 can operate within 100% duty cycle.
The KA3884 and KA3885 within 50% by using T Flip-Flop.
