TECHNICAL DATA

PWM Control Circuit

IL494

The IL494 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

IL494 contains an on-chip 5-volt regulator, two error amplifiers,

adjustable oscillator, dead-time control comparator, pulse-steering

flip-flop, and output-control circuitry. The uncommitted output

transistors provide either common-emitter or emitter-follower output

capability. Push-pull or single-ended output operation may be

selected through the output-control function. The architecture of the

IL494 prohibits the possibility of either output being pulsed twice

during push-pull operation.
