This application note outlines the performance of PWM margining when the MAX34451 is connected to the MAX15041 evaluation (EV) kit:
Pulse-width modulation (PWM) margining is a simple technique to adjust the output voltage of power supplies. This application note discusses the effect of PWM on the power-supply output-voltage noise, the enabling and disabling of PWM, and the impact of the PWM lowpass filter. The MAX34451 system manager and the MAX15041 evaluation (EV) kit are used in this discussion.
