MP5505E

7V, 4A, High-Efficiency, Energy Storage and Management Unit

Datasheet

Description

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.

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.

The MP5505E requires a minimal number of readily available, standard, external components and is available in a QFN-20 (3mmx4mm) package.

EV5505E-L-00AEvaluation Board is designed to demonstrate the capabilities of MP5505E. MP5505E is designed to provide back-up power in the event of a power loss. 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. MPS’ patented power back-up 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 requirements.
