The EVQ4491M-RE-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MPQ4491M. MPQ4491M integrates a monolithic step-down switch mode converter and one USB current limit switch with charging port identification circuit. It achieves 2.5A continuous output current over a wide input supply range with excellent load and line regulation.
The output of USB switch is current limited. MPQ4491M provides a USB Dedicate Charging Port (DCP) which supports Battery Charging Specification 1.2 (BC1.2), the Divider Mode, and 1.2V/1.2V Mode without the need of outside user interaction.
