ABSTRACT:
A pulse width modulator is provided with circuitry to eliminate high frequency noise spikes in its output. This circuitry is effective to slow down the switching time of the MOSFET switching transistor, increase the rise time of the voltage across the catch diode and improve the high frequency characteristics of the output filter. These benefits are achieved by only a few number of components.
