| Input voltage | 15-72 V |
| Output 1 | 12 V / 8 A |
Description
The LM5149Q1EVM-400 evaluation module (EVM) is a synchronous buck DC/DC regulator with constant-current constant-voltage (CCCV) regulation. The EVM operates over a wide input voltage range of 15V to 72V (at J1 VIN terminal), providing a regulated current of 8A in CC mode and a regulated voltage of 12V in CV mode. The regulation target of the average inductor current is programmed by ISET, and the output voltage is adjusted by modifying the feedback resistors.
