CURRENT

−−MODE PWM CONTROLLER

The KA3842A

are fixe frequency current-mode

PWM controller. They are specially designed for OFF

−Line and DC−to−DC converter

applications with minimal external components. These integrated circuits feature a

trimmed oscillator for precise duty cycle control, a temperature compensated reference,

high gain error amplifier, current sensing comparator, and a high current totempole

output ideally suited for driving a power MOSFET.

Protection circuity includes built under

−voltage lockout and current limiting.
