The Future of Analog IC Technology
DESCRIPTION
The MP3423 is a high-efficiency, synchronous,
current-mode, step-up converter with output
disconnect.
The MP3423 starts up from an input voltage as
low as 1.9V, while providing inrush current
limiting and output short-circuit protection. The
integrated P-channel synchronous rectifier
improves efficiency and eliminates the need for
an external Schottky diode. This P-channel
disconnects the output from the input during
shutdown.
The 600kHz switching frequency allows small
external components, while the internal
compensation and soft-start minimize external
component count. The MP3423 provides a
compact solution for a 5V output, 3.1A load
requirement, using a supply voltage down to
2.8V.
The MP3423 is available in 14-pin QFN
2mmx2mm package.
