MP5505E 7V, 4A, High-Efficiency, Energy Storage and Management Unit DESCRIPTION The MP5505E is a lossless energy storage and management unit targeted toward solid-state and hard-disk drive applications. The highly integrated input current limit and energy storage-and-release management make 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, and a power-on reset function is included for hot-swapping. MPS’s patented energy storage-and-release management control circuit minimizes the storage capacitor requirement.
