Product Description

EV5455-L-00AEvaluation Board is designed to demonstrate the capabilities of MP5455. The MP5455 is designed as a peak power assist for low power applications, releasing energy as needed during peak loading events. 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’s 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.

The MP5455 is available in a space QFN20 (3mmX4mm) package.

Parametrics


4.5A, 7V, Power Back-Up Management

The MP5455 is designed to provide back-up power in the event of a power failure. 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’s patented power back-up control circuit minimizes the storage capacitor requirement. This control circuit 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.
The MP5455 requires a minimal number of readily available, standard, external components and is available in a QFN-20 (3mmx4mm) package.


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

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×4mm) package.
