DESCRIPTION

The MP1400 is a monolithic negative DCDC

power converter with built-in internal power

MOSFET. The DC-DC IC has a tiny surface

mount 0.8mm x 1.6mm 8-ball CSP package. It

achieves up to 600mA peak output current from

a 2.7V to 7V input voltage. The output voltage

can be regulated from -0.9V to

-6V.

The 1500 kHz switching frequency allows for

smaller external components producing a

compact solution for a wide range of load

currents. The internal compensation and soft

start minimizes the external component count

and limits the inrush current during startup.

Fault condition protection includes cycle-by-

cycle current limiting and thermal shutdown.
