Beschreibung

The EV2720-RH-00A is an evaluation board designed to demonstrate the capabilities of the MP2720, a highly-integrated, 2.5A, switchmode battery management device for a singlecell Li-ion or Li-polymer battery. The narrowvoltage DC (NVDC) power management structure provides a low-impedance power path that optimizes charging efficiency, reduces battery charging time, and extends battery life during discharging.
