The EV3431-L-00A evaluation board is designed to demonstrate the capability of the MP3431. The MP3431 is a 600kHz, fixed-frequency, wide input range, highly integrated boost converter. It starts from an input voltage as low as 2.7V, and supports up to 30W of load power from a single-cell battery.

The MP3431 adopts constant-off-time (COT) control topology providing fast transient response. The MODE pin supports mode selection including PSM, FCCM, and USM in light-load conditions, and the integrated LS-FET and HS-FET simplify the design and save BOM cost.

The device features programmable input current limit to provide accurate overload protection while the LS-FET limits cycle-by-cycle inductor peak current. It also features programmable input UVLO and over-temperature protection. The MP3431 is available in a QFN-13 (3mmx4mm) package.
