Description
The MAX25203 evaluation kit (EV kit) is a fully assembled and tested board for evaluating the MAX25203 dualphase automotive synchronous boost controller. The MAX25203 enables infotainment systems to stay in regulation during cold crank or start-stop operation all the way down to battery input of 1.8V. It can also be used to generate backlight voltage and class D audio amplifier voltages. This device can start with an input voltage supply from 4.5V to 42V and can operate down to 1.8V after start-up and has a low 5µA shutdown supply current.
The MAX25203 features a power-OK monitor, overvoltage and undervoltage lockout. Protection features include cycle-by-cycle current limit and thermal shutdown. It is specified for operation over the -40°C to +125°C automotive temperature range.
