MPQ4475-E - Step-Down Converter

Description

The MPQ4475-E integrates a monolithic, stepdown, switch-mode converter with a single USB current-limit switch and charging port identification circuit.

The MPQ4475-E achieves 2.5A of continuous output current with excellent load and line regulation over a wide input supply range.

Features

  • include hiccup current limiting, output over-voltage protection (OVP), and thermal shutdown. The MPQ4475-E requires a minimal number of readily available, standard, external components and is available in a QFN-25 (4mmx4mm) package.

The Future of Analog IC Technology MPQ4475-E 36V, 2.5A, Frequency Selectable, Step-Down Converter with Single USB Charging Port AEC-Q100 Qualified DESCRIPTION The MPQ4475-E integrates a monolithic, stepdown, switch-mode converter with a single USB current-limit switch and charging port identification circuit. The MPQ4475-E 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-E 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.
