Evaluation Kits

MAX25601EVKIT

Evaluation Kit for the MAX25601A, MAX25601B, MAX25601C, MAX25601D

Features and Benefits

  • Configured for Pre-Boost and Buck Application
  • Analog Dimming Control
  • Proven PCB Layout
  • Fully Assembled and Tested

Product Details

The MAX25601 evaluation kit (EV kit) provides a proven design to evaluate the MAX25601A/MAX25601C automotive high-voltage, high-brightness LED (HB LED) boost-buck controller. The front-end pre-boost operates from a 7.7V to 18V DC supply voltage, generating a 48V output. The buck supports 12x LEDs and lower, delivering up to 1.5A to one string of LEDs. The total voltage of the string can vary from 3V to 36V.

Applications

  • Automotive Exterior Lighting: High-Beam/Low-Beam/ Signal/Position Lights, Daytime Running Lights (DRLs), Matrix Light, Pixel Light, and Other Adaptive Front-Light Assemblies
  • Commercial, Industrial, and Architectural Lighting
