8.2.2.1 Design Requirements

Table 8-3 shows the intended input, output, and performance parameters for this application example. With an IBB topology, the module sees a total current of IIN + |–IOUT|, which is highest at minimum input voltage.

Table 8-3 Design Parameters
DESIGN PARAMETERVALUE
Input voltage range9 V to 24 V
Input voltage UVLO turn on8.9 V
Output voltage–12 V
Full-load current–5 A
Switching frequency1 MHz
Output voltage regulation±1%

Table 8-4 gives the selected buck module power-stage components with availability from multiple vendors. This design uses an all-ceramic output capacitor implementation.
