Product Description

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.

IC Details

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 of load current with an extremely low RDS(ON). With an input range of up to 6V, the MP5403 is ideal for powering ASIC and SOC for solid-state drives and other compact power systems.
The peak-current-mode control scheme with pulse-skip-mode operation provides the two switchers with fast transient response, high light-load efficiency, and minimum capacitance by using an interleaving PWM clock between the two switchers. The 3A load switch with a low 20mΩ on resistance provides flexible system configuration.
A full set of enable control pins and power good open-drain indicators allow for easy implementation of the start-up and shutdown sequences.
Full protection features include over-current protection (OCP) and thermal shutdown.
The MP5403 requires a minimal number of readily available, standard, external components and is available in a small UTQFN-20 (2.5mmx3mm) package.
