PWM Control Circuit
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.
Complete PWM Power Control Circuitry
Uncommitted Outputs for 200 mA Sink or Source
Output Control Selects Single-Ended or Push-Pull Operation
Internal Circuitry Prohibits Double Pulse at Either Output
Internal Regulator Provides a Stable 5 V Reference Supply
Variable Dead-Time Provides Control Over Total Range
