KK494, PWM Control Circuit

www.DataSheet4U.com TECHNICAL DATA PWM Control Circuit The KKK494 incorporates on a single monolithic chip all the functions required in the construction of a pulse-width-modulation control circuit.

Designed primarily for power supply control, the KK494 contains an onchip 5-volt regulator, two error amplifiers, adjustable oscillator, deadtime control comparator, pulse-steering flip-flop, and output-control circuitry.

The uncommitted output transistors provide either commonemitter or emitter-fo
