Monolithic Power Systems MP5455 | Demoboard EV5455-L-00A

Beschreibung

EV5455-L-00A Evaluation Board is designed todemonstrate the capabilities of MP5455. TheMP5455 is designed to provide back-up powerin the event of a power loss. The internal inputcurrent-limit block with dv/dt control preventsinrush current during system start-up; the busvoltage start-up slew rate is programmable.MPS’ patented power back-up control circuitminimizes the storage capacitor requirement. Itpumps the input voltage to a higher storagevoltage and releases the energy over a hold-uptime to the system in the case of an inputoutage. The storage voltage and the releasevoltage are both programmable for differentsystem requirements.
