Product Description

The EVQ4475-R-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MPQ4475. MPQ4475 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. MPQ4475 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.

IC Details

The MPQ4475 integrates a monolithic, step-down, switch-mode converter with a single USB current-limit switch and a charging port identification circuit. The MPQ4475 achieves 2.5A of continuous output current with excellent load and line regulation over a wide input supply range.

The output of the USB switch is current-limited. The MPQ4475 provides a USB-dedicated charging port (DCP), which supports battery charging specification 1.2 (BC1.2), divider mode, and 1.2V/1.2V mode without the need for outside user interaction. The output voltage has programmable line drop compensation.

Full protection features include hiccup current limiting, output over-voltage protection (OVP), and thermal shutdown.

The MPQ4475 requires a minimal number of readily available, standard, external components and is available in a QFN-25 (4mmx4mm) package.
