Evaluation Tools

EV5403-QB-02A Evaluation Kit High Efficiency Dual Buck and One Load Switch Power Management Unit EV Board
The EV5403-QB-02A Evaluation Board is designed to demonstrate the capabilities of MPS’ MP5403. The MP5403 is a monolithic power management unit containing two high efficiency step-down switching converters and a load switch. The two regulators supply current up to 3.5A and 2.5A separately and the load switch supplies up to 3A load current with extremely low RON resistance. With the input range up to 6V, the MP5403 is ideal for powering ASIC and SOC for Solid-State Drive or other compact power systems.
The MP5403 requires a minimum number of readily available standard external components and is available in a small QFN20 (2.5mmx3mm) package.
