Product Details

The MAX15258 evaluation kit (EV kit) provides a proven design to evaluate the MAX15258, a high-voltage multiphase boost controller with I²C digital interface designed to support up to four MOSFET drivers and eight external MOSFETs in a single-phase, dual-phase, triple-phase, or quad-phase inverting-buck-boost configuration using discrete inductors. The EV kit operates from a -36V to -60V input voltage range and supports a 24V to 50V output voltage range. The EV kit uses the MAX15258 on a proven six-layer PCB design. Two MAX15013 ICs are used as the MOSFET driver for the EV kit. The EV kit also features an onboard MAX17760 buck converter to provide a 10V supply voltage to the MAX15258 and the MOSFET drivers. An external MAX32625PICO board is used to communicate between the MAX15258 and MAX15258 GUI. Two MAX15258 EV kits are required for triple-phase or quad-phase operation.
