SLVSGU1A November 2022 – December 2023 TPSM63610
PRODUCTION DATA
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.
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.
