TYPICAL APPLICATION SCHEMATIC

Figure 3 shows the UCD9244 power supply controller as part of a system that provides the regulation of two

independent power supplies. The loop for each power supply is created by the respective voltage outputs feeding

into the differential voltage error ADC (EADC) inputs, and completed by DPWM outputs feeding into the gate

drivers for each power stage.

The

output power stage. For example, the power stage driven by DPWM1A must have its feedback routed to EAP1

and EAN1.
