DESCRIPTION

EV3429-L-00A Evaluation Board is designed to

demonstrate the capability of 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 1-cell

battery.

MP3429 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 LS and HS MOSFET simplify the

design and save BOM cost.

The MP3429 also features with programmable

input UVLO and over temperature protection.

The MP3429 is available in a 13-pin 3mmx4mm

QFN package.
