S494 Datasheet (AUK corp) - Pulse Width Modulation

S494, Pulse Width Modulation

The S494 is a monolithic integrated circuit which includes all the necessary building blocks for the design of pulse width modulate(PWM) switching power supplies, including push-pull, bridge and series configuration.

The device can operate at switching frequencies between 1KHz and 300KHz and output

S494 Features

* Uncommitted output transistors capable of 200mA source or sink

* Internal protection from double pulsing of out-puts with narrow pulse widths or with supply voltages bellows specified limits

* Easily synchronized to other circuits

* Dead time control comparator
