8.2.1.1 Design Requirements

Table 8-3 shows the intended input, output, and performance parameters for this application example. Note that if the input voltage decreases below approximately 6 V, the regulator operates in dropout with the output voltage below its 5-V setpoint.

Table 8-1 Design Parameters
DESIGN PARAMETER VALUE
Input voltage range 9 V to 36 V
Input voltage UVLO turn on, off 6 V, 4.3 V
Output voltage 5 V
Maximum output current 8 A
Switching frequency 1 MHz
Output voltage regulation ±1%
Module shutdown current < 1 µA

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.
