Figure 27. Typical Application Schematic
A. This discrete bias power circuit may be substituted with a low dropout regulator (LDO). For example, TPS715A33
can provide bias power to the UCD9240.
Figure 27 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 PTD08A0x0W modules.
