STC494 Datasheet (Suntac Electronic) - Pulse Width Modulation

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.

The device can operate at switching frequencies between 1KHz and 300KHz and outpu
