KK494 Datasheet PDF | Kodenshi AUK Group

Kodenshi AUK Group KK494

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-follower output capability. The architecture of the KK494 prohibits the possibility of either output being pulsed twice during push-pull operation.
