The Future of Analog IC Technology
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.
