GL494 Overview
The GL494 incorporates on a single monolithic chip all the functions required in the construction of a pulse-widthmodulation control circuit. Designed primarily for power supply control, the GL494 contains an on-chip 5-volt regulator, two error amplifiers, adjustable oscillator, deadtime control parator, pulse-steering flip-flop, and output-control circuitry. The unmitted output transistors pro-vide either...
