DESCRIPTION

MP5512 is a high-efficiency energy storage and

management unit targeting solid-state and

hard-disk

drive

applications.

Its

highly

integrated

input-current

limit

and

energy

storage and release management provide an

efficient, compact system solution for SSD

applications.

The internal input-current-limit block with dv/dt

control prevents an inrush current during

system start-up. The bus voltage start-up slew

rate is programmable; it includes a power-on-

reset function for hot-swapping. MPS’ patented

energy-storage

and

release-management

control circuit minimizes the storage capacitor

requirement. It boosts the input voltage to a

higher storage voltage and releases the energy

over a hold-up time in case of an input outage.

The storage voltage and the release voltage are

both

programmable

for

different

system

applications.

The MP5512 requires a minimal number of

standard, external components and is available

in a 28-pin QFN (4mm×5mm) package.
