The EVQ4475-E-R-00A evaluation board is designed to demonstrate the capabilities of the MPQ4475-E. The MPQ4475-E integrates a monolithic, step-down, switch-mode converter and one USB current-limit switch with a charging port identification circuit. It achieves 2.5A of continuous output current over a wide input supply range, with excellent load and line regulation.

The output of USB switch is current limited. The MPQ4475-E provides a USB dedicated charging port (DCP) that supports Battery Charging Specification 1.2 (BC1.2), divider mode, and 1.2V/1.2V mode without the need for outside user interaction.
