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.

EV5505A-L-00AEvaluation Board is designed to demonstrate the capabilities of MP5505A. The MP5505A is front end power and data backup power management Unit IC for SSD application. It supports input hot swap, input startup inrush current control, input current limit, power on reset and backup power management for SSD data backup in case of input power failure. MP5505A’s built-in boost mode converter charges energy storage bulk capacitor to a programmed voltage level (up to 30V) when system is powered up and keeps refreshing the charge during normal operation. In case of input power failure, MP5505A flags the input power failure, disconnects input power and transfers the energy from energy storage bulk capacitor to SSD system’s DCDC switches via built-in buck mode converter to keep SSD system powered for data backup.
The MP5505A requires a minimum number of readily available standard external components and is available in a space QFN20 (3mmX4mm) package.
