High-Efficiency, Synchronous Boost Converter with Programmable Current Limit Evaluation Board
The EV3432-L-00A evaluation board is designed to demonstrate the capability of teh MP3432. The MP3432 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 MP3432 adopts constant-off-time (COT) control topology providing fast transient response. One MODE pin supports mode selection of PSM, FCCM, and USM in light-load conditions. The integrated low-side and high-side MOSFET simplify the design and save BOM cost.
The device features programmable switching peak current limit and provides accurate overload protection. It also features programmable input UVLO and over-temperature protection. The MP3432 is available in a QFN-13 (3mmx4mm) package.

Fully Integrated, Synchronous, 30W Boost Converter with Pass-through Mode and Programmable Switching Current Limit
The MP3432 is a 600kHz, fixed frequency, wide input range, highly integrated, boost converter. The MP3432 starts from an input voltage as low as 2.7V and supports up to 30W of load power from a 1-cell battery with integrated low RDS(ON) power MOSFETs.
The MP3432 adopts constant-off-time (COT) control topology, which provides fast transient response. MODE supports the selection of pulse-skip mode (PSM), forced continuous conduction mode (FCCM), and ultrasonic mode (USM) in a light-load condition. The programmable switching peak current limit provides accurate overload protection. And the high-side MOSFET eliminates the need for an external Schottky diode.
Full protection features include programmable input under-voltage lockout (UVLO) and over-temperature protection (OTP).
The MP3432 is available in a QFN-13 (3mmx4mm) package.
