Input voltage range | 9 V to 24 V |
Input voltage UVLO turn on | 8.9 V |
Output voltage | –12 V |
Full-load current | –5 A |
Switching frequency | 1 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.
