Texas Instruments LM5190Q1EVM-400 Evaluation Module (EVM)

Texas Instruments LM5190Q1EVM-400 Evaluation Module (EVM) is a synchronous buck DC-DC regulator with constant-current constant-voltage (CCCV) regulation. The Texas Instruments LM5190Q1EVM-400 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.

Features

  • 15V to 72V input voltage range
  • 12V output voltage in CV mode
  • 8A output current in CC mode
