MP5512GV Datasheet | Monolithic Power Systems

The Future of Analog IC Technology MP5512 18V, 4.5A, High-Efficiency Energy Storage and Management Unit for SSD Applications DESCRIPTION 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, pact 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-onreset function for hot-swapping. MPS’ 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 ponents and is available in a 28-pin QFN (4mm×5mm) package.
