DESCRIPTION

The

EV1400-C-01A

demonstrates

MPS’s

MP1400, a monolithic negative DCDC power

converter with built-in internal power MOSFET.

It offers a very compact solution to achieve up

to 600mA continuous output current depending

on input-voltage to output-voltage ratio. 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.

Fault condition protection includes cycle-by-

cycle current limiting and thermal shutdown.

The MP1400 is available in a 0.8mm x 1.6mm

8-ball CSP package.
