The EVL5516-R-00A is an evaluation board designed to demonstrate the capabilities of the MP5516, a monolithic power management IC (PMIC) that is ideal for power management and conditioning in enterprise solid-state drive (SSD) applications.

The MP5516 consists of an input current limit switch (e-fuse) and a bidirectional buck-boost converter. The e-fuse features a low on resistance (R_DS(ON)), current limiting, and reverse-current blocking. The buck-boost converter manages energy storage and energy release.

The e-fuse’s configurable current limit prevents inrush current during start-up. Reverse-current blocking prevents backup energy from flowing to the failing input voltage (V_IN) port, which allows the backup energy to be utilized during a power outage. Backup energy is stored in the storage capacitors.

The configurable charge current controls the rate at which the storage voltage (V_STORAGE) ramps up. Constant-on-time control (COT) minimizes the voltage dip during the transition from boost charge mode to buck release mode.

The MP5516 also provides a digital I²C interface and internal analog-to-digital converter (ADC). The I²C can set the input current limit and perform capacitor health tests. The ADC monitors V_IN, the input current (I_IN), and the input power (P_IN).

The MP5516 requires a minimal number of readily available, standard external components, and is available in a QFN-25 (4mmx4mm) package.
