DESCRIPTION
The MP3422 is a high-efficiency, synchronous,
current–mode, step-up converter with output
disconnect.
The MP3422 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 MP3422 provides a
compact solution for a 5V output, 2.5A load
requirement, using a supply voltage down to
2.8V.
The MP3422 is available in 14-pin QFN
2mmx2mm package.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation a
t
any ambient temperature is calculated by P
D
(MAX) = (T
J
(MAX)-T
A
)/
JA
. Exceeding the maximum allowable powe
r
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanen
t
damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer PCB.
