Figure 28. Typical Application Schematic
UDG-08036
Figure 28 shows the UCD9240 power supply controller working in a system which requires the regulation of four
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 into the UCD7230 drivers which
are shown on the PTD08A010W and PTD08A020W modules.
