STC494 Pulse Width Modulation
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!
