Description
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. The device can operate at switching frequencies between 1KHz and 300KHz and output voltage up to 40V. The STC494 is specified over an operating temperature range of -40к to 85к .

FEATUREs
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
