Product Details

The MAX25249 evaluation kit (EV kit) is a fully assembled and tested application circuit for the MAX25249/ MAX25249B high-efficiency four-output mini PMICs designed to power camera applications. The EV kit can test each of the outputs to full load. The output voltage accuracy is ±1.5% for all outputs within the normal operation input range of +4.5V to +36V. There is a active-low RESET signal to monitor overvoltage and undervoltage with ±1.3% accuracy. The MAX25249BEVKIT# is also available, and comes pre-installed with the MAX25249BATPB/VY+ IC.

Applications

  • Front/Rear/Surround View Camera
