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 pact. 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 ponents and is available in a QFN-20 (3mm x 4mm) package.
