EVL5516-R-00A

MPL Optimized Performance with MPS Inductor 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 (RDS(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 (VIN) 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 (VSTORAGE) 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 VIN, the input current (IIN), and the input power (PIN). The MP5516 requires a minimal number of readily available, standard external components, and is available in a QFN-25 (4mmx4mm) package.
