MP5512GV-Z

The MP5512 is a high-efficiency energy storage and management unit targeting solid-state and hard-disk drive applications. Its highly integrated input-current limit and energy storage and release management provide an efficient, compact system solution for SSD applications.

The internal input-current-limit block with dv/dt control prevents an inrush current during system start-up. The bus voltage start-up slew rate is programmable; it includes a power-on-reset function for hot-swapping. The patented energy-storage and release-management control circuit minimizes the storage capacitor requirement. It boosts the input voltage to a higher storage voltage and releases the energy over a hold-up time in case of an input outage. The storage voltage and the release voltage are both programmable for different system applications.

The MP5512 requires a minimal number of standard, external components and is available in a 28-pin QFN (4mm×5mm) package.
