EV3429-L-00A Evaluation Kit 21A, High-Efficiency, Fully Integrated Synchronous Boost Converter Evaluation Board
The EV3429-L-00A evaluation board is designed to demonstrate the capability of teh MP3429. The MP3429 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 load power from a single-cell battery.
The MP3429 adopts constant-off-time (COT) control topology to provide 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 IC also features with programmable input UVLO and over-temperature protection. It is available in a QFN-13 (3mmx4mm) package.
