MP5505E

7V, 4A, High-Efficiency,

Energy Storage and Management Unit

DESCRIPTION

FEATURES

The MP5505E is a lossless energy storage and

management unit targeted toward solid-state

and hard-disk drive applications. The highly

integrated input current limit and energy

storage-and-release management make the

system solution very compact.



Wide 2.7V to 7V Operating Input Range

Input Current Limiter with Integrated 60mΩ

MOSFET

Up to 4.5A Input Current Limit

Reverse-Current Protection

6V Bus Clamping Voltage

Power-On Reset

Adjustable dV/dt Slew Rate for Bus Voltage

Start-Up

Internal 30mΩ Disconnect Switch

Internal 70mΩ and 60mΩ Power Switches

for Energy Storage and Release

Management Circuits



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, and a power-on reset function is

included for hot-swapping. MPS’s 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.



Thermal Protection

EN and Power Good Indicators

Available in a QFN-20 (3mmx4mm)

Package

APPLICATIONS



Solid-State Drives (SSD)

Hard-Disk Drives

Power Back-Up/Battery Hold-Up Supplies

The MP5505E requires a minimal number of

readily

available,

standard,

external

components and is available in a QFN-20

(3mmx4mm) package.

All MPS parts are lead-free, halogen-free, and adhere to the RoHS
