Product Description

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.

High-Efficiency, SYNC, BOOST Converter with Programmable Current Limit EV Board

EV3432-L-00A Evaluation Board is designed to demonstrate the capability of 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 1-cell battery.

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 condition. And the integrated low-side and high-side MOSFET simplify the design and save BOM cost.

The MP3432 features with programmable switching peak current limit provides accurate over load protection. And it also features with programmable input UVLO and over temperature protection.

The MP3432 is available in a 13-pin 3mmx4mm QFN package.
