MP5505GL-P

MP5505 is a lossless energy storage and management unit targeted at the 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. It also includes a Power-OnReset function for hot-swapping. MPS’s 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 MP5505 requires a minimal number of readily-available standard external components, and is available in a 20-pin QFN (3mm×4mm) package.
