DESCRIPTION
EV3423-G-00A Evaluation Board is designed to
demonstrate the capability of MP3423. MP3423
is a high-efficiency, synchronous, current-mode,
step-up converter with output disconnect.
The MP3423 can provide small size solution for
5V/3.1A load from a supply voltage down to
2.8V. The integrated P-channel synchronous
rectifier improves efficiency and eliminates the
need for an external Schottky diode. The PMOS
disconnects the output from the input when the
part shuts down.
The 600kHz switching frequency allows for
small external components, while the internal
compensation and soft-start minimize the
external component count. The MP3423 is
available in 14-pin QFN 2mmx2mm package.
