EV2733-QC-00A

Wide-Input, 4.5A, I2C-Controlled SW Charger with NVDC Power Path Management and USB OTG Evaluation Board

Description

The EV2733-QC-00A is an evaluation board designed to demonstrate the capabilities of the MP2733. The MP2733 is a wide-input, 4.5A, highly integrated switch-mode battery charger IC for single-cell Li-ion or Li-polymer batteries.

This device supports narrow voltage DC (NVDC) architecture with power path management. It is well-suited for portable applications, such as tablets, mobile internet devices, and smartphones. The device’s low impedance power path
optimizes efficiency, reduces battery charging time, and extends battery life. The I2C serial interface allows the user to flexibly control the device by changing charging and system settings.

The EV2733-QC-00A supports input sources up to 16V, including standard USB host ports and high-voltage wall adapters with fast charge capability. The EV2733-QC-00A supports USB On-the-Go (OTG) operation by supplying 5V with 3.0A.
