STC494 - Pulse Width Modulation

The STC494 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.

• ΘUncommitted output transistors capable of 200mA source or sink! ΘInternal protection from double pulsing of out-puts with narrow pulse widths or with! supply voltages bellows specified limits! ΘEasily synchronized to other circuits! ΘDead time control comparator! ΘOutput control selects single-ended or push-pull operation! Ordering Information Type NO.
