The MP5515 is an input power conditioning PMIC targeting enterprise solid-state drives, NVDIMM, and other applications with back-up system requirements. The MP5515 consists of input current limiting, input reverse current blocking, and an MPS-patented, high-efficiency, bidirectional, boost-buck converter with only one inductor for energy storage and system back-up power when there is an input power failure. The MP5515 also provides I2C interface and ADC. By using the I2C, users can set the input current limit, slew rate, and perform cap health tests. The MP5515 can also monitor system status, such as input voltage, input current, storage voltage, temperature, and provide interrupt options for these features.
The internal input current-limit block prevents inrush current during system start-up while the reverse-current block prevents backup energy from flowing to the failing VIN port. MPS’s patented energy storage and release management control circuit minimizes the storage capacitor requirement. It pumps the input voltage to a higher backup voltage and releases the energy over a hold-up time to the system bus voltage in case of an input outage.
The MP5515 requires a minimal number of standard, external components and is available in a 30-pin QFN (5mmx5mm) package.

EVKT-5515 Evaluation Kit 2.7 - 18V, 5A, Bidirectional, Power Back-Up Manager with Integrated Hot-Swap
The MP5515 is an input-power-conditioning PMIC targeting enterprise solid-state drives, NVDIMM, and other applications with back-up system requirements. The MP5515 consists of input current limiting, input reverse-current blocking, and an MPS-patented, high-efficiency, bidirectional, boost-buck converter with only one inductor for energy storage and system back-up power when there is an input power failure.
Highly customizable, the MP5515 is capable of supporting a diverse array of mid-voltage applications. Users can program it via an MPS I2C GUI; however, changes made in I2C mode will not be retained once the EVB is powered down.
The EVKT5515 is a valuable evaluation tool well-suited for all types of experience levels, from beginner to expert, and can help users quickly determine if the MP5515 is right for their target application.
