Datasheet Summary
Semiconductor
Pulse Width Modulation
Description
The S494 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 S494 is specified over an operating temperature range of -40℃to85℃.
Features
- Unmitted output transistors capable of 200mA source or sink
- Internal protection from double pulsing of out-puts with narrow pulse widths or with supply voltages bellows specified limits
- Easily synchronized to other circuits
- Dead...
