EV2762A-V-00A

6A Buck or Boost Charger with NVDCPower Management and USB OTG for 2 Cells in Series Batteries Evaluation Board

New

Description

The EV2762A-V-00A is an evaluation board for the MP2762A, a highly integrated buck or boost charger IC with narrow-voltage DC (NVDC) power path management and USB On-the-Go (OTG) for battery packs with two cells in series. All power MOSFETs are integrated to provide an easy-to-use, compact system solution.

The IC can accept a wide range of input voltages for charging, with a maximum of 21V. The device has two operating modes during the charging process: boost charging mode and buck charging mode. In boost charging mode, two buck phases are in parallel, and the high-side MOSFET is always on in each phase. In buck charging mode, two interleaving buck phases simplify inductor selection by allowing for a smaller profile and reduced output current ripple.

The MP2762A provides a 4.75V to 5.5V input voltage range in USB OTG mode. The device utilizes a single-phase buck converter to provide 5V/3A from the battery pack.

The MP2762A is available in a QFN-30 (4mmx5mm) package.
