EV5455-L-00AEvaluation Board is designed to demonstrate the capabilities of MP5455. The MP5455 is designed as a peak power assist for low power applications, releasing energy as needed during peak loading events. The internal input-current-limit block with dv/dt control prevents inrush current during system start-up; the bus voltage start-up slew rate is programmable. MPS’s patented power back-up control circuit minimizes the storage capacitor requirement. It pumps the input voltage to a higher storage voltage and releases the energy over a hold-up time to the system in the case of an input outage. The storage voltage and the release voltage are both programmable for different system requirements.
The MP5455 is available in a space QFN20 (3mmX4mm) package.
