SL494 Description
SL494 PWM Control Circuit The SL494 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 SL494 contains an on-chip 5-volt regulator, two error amplifiers, adjustable oscillator, dead-time control parator, pulse-steering flip-flop, and output-control circuitry. The unmitted output...
