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 voltage up to 40V.

Uncommitted output transistors capable of 200mA source or sink Internal protection from double pulsing of output with narrow pulse widths or with supply voltages bellows specified limits Easily synchronized to other circuits Dead time control comparator Output control selects single-ended or push-pull operation   SMPS   Company AUK FKS ST KEC Item No. S494 TL494 TL494 TL494
