CE161 - True Independent PWM Output Mode using dsPIC33F SMPS DSC

Microchip Technology

The dsPIC SMPS Family of Digital Signal Controllers feature an on-chip Power Supply PWM Module. This module supports several PWM modes typically used in Power Conversion applications. One mode shown here is the True Independent PWM Ouptut Mode.This example is intended to provide a setup guide for using this mode.

About this Code Example

The dsPIC SMPS Family of Digital Signal Controllers feature an on-chip
Power Supply PWM Module. This module supports several PWM modes typically
used in Power Conversion applications. One mode shown here is the
True Independent PWM Ouptut Mode.This example is intended to provide a setup guide
for using this mode.

PWM1H and PWM1L have different switching frequencies but the same duty cycle
(50% of switching period). To verify the independent output feature of the PWM module connect
oscilloscope probes to PWM1H and PWM1L.
