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 .
