Product Details

The MAX20030 evaluation kit (EV kit) is a fully assembled and tested application circuit for the MAX20030 highvoltage, dual-synchronous step-down controller IC with preboost and an internal LDO. The EV kit is set up to provide 5V and 3.3V from an input voltage ranging from 3.5V to 36V. The preboost circuit maintains the 10V supply rail for input voltages below 10V. Each buck rail can deliver up to 5A load current. Various jumpers are provided to help evaluate features of the IC. The EV kit can also be used to evaluate the pin-compatible MAX20031 with IC replacement of U1.
