MP5505A
7V, 4A, High-Efficiency Energy Storage and
Management Unit
The Future of Analog IC Technology
DESCRIPTION
The MP5505A is a lossless energy storage and
management unit targeted at solid-state and
hard-disk drive applications. Its highly integrated
input current limit and energy storage and
release management makes the system solution
very compact.
The internal input-current-limit block with dv/dt
control prevents inrush current during system
start-up; the bus voltage start-up slew rate is
programmable. Also, 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
pumps the input voltage to a higher storage
voltage and releases the energy over a hold-up
time to the system in the case of an input outage.
The storage voltage and the release voltage are
both programmable for different system
applications.
The MP5505A requires a minimal number of
readily available, standard, external components
and is available in a QFN-20 (3mm x 4mm)
package.
