Description

MPL

Optimized Performance with MPS Inductor

The MP5516 is a monolithic power management solution designed to manage energy storage and release in enterprise solid-state drives (SSDs). It integrates an input current limit (I_{LIMIT_E-FUSE}) switch and a bidirectional buck-boost converter for energy management. The e-fuse features a low on resistance (R_DS(ON)), current limiting, and reverse-current blocking.

The configurable I_{LIMIT_E-FUSE} prevents inrush current during start-up. Reverse-current blocking prevents backup energy from flowing to the failing input voltage (V_IN) port to fully utilize the backup energy during a power outage.

Backup energy is stored in the storage capacitors. MPS’s patented energy storage and release management control circuit minimizes the storage capacitor requirement. The IC provides a high storage voltage (V_STRG) to store energy in capacitance. If an input outage occurs, this energy is released to the system during a hold time (t_HOLD). V_STRG and the buck release voltage (V_{BUCK_RLS}) are both configurable for different system applications.

The configurable charge current (I_CHARGE) is provided to ramp up V_STRG in a controllable manner. Constant-on-time (COT) control reduces the voltage dip during the transition between boost charge mode and buck release mode. Only one inductor is required, which minimizes the total solution size.

The device also features an I²C interface and an internal analog-to-digital converter (ADC). I_{LIMIT_E-FUSE} can be configured via the I²C. The I²C can also perform capacitor health tests. The internal ADC monitors the input voltage (V_IN), input current (I_IN), and 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.

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 (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.
