Figure 22 shows the UCD9220 power supply controller working with a single PTD08D210W, dual-output module
regulating two independent power supplies. The loop for each power supply is created by the respective voltage
outputs feeding into the Error ADC differential inputs, and completed by DPWM outputs feeding the
PTD08D210W module.
