MPQ4488B - Step-Down Converter

General Description

The MPQ4488B integrates a monolithic, stepdown, switch-mode converter with two USB current-limit switches and charging port identification circuitry for each port.

The MPQ4488B achieves 6A of output current, with excellent load and line regulation over a wide input supply range.

Key Features

  • include hiccup current limiting, output over-voltage protection (OVP), and thermal shutdown. The MPQ4488B requires a minimal number of readily available, standard external components, and is available in a QFN-26 (5mmx5mm) package.

MPQ4488B 36V, 6A, Step-Down Converter with Programmable Frequency, Spread Spectrum Dual USB Charging Ports, AEC-Q100 Qualified DESCRIPTION The MPQ4488B integrates a monolithic, stepdown, switch-mode converter with two USB current-limit switches and charging port identification circuitry for each port. The MPQ4488B achieves 6A of output current, with excellent load and line regulation over a wide input supply range. The output of each USB switch is current-limited. Both USB ports support DCP schemes for battery charging specification (BC1.2), Apple 3A Divider mode, 1.2V/1.2V mode, and USB TypeC 5V @ 3A DFP mode, eliminating the need for outside user interaction. Full protection features include hiccup current limiting, output over-voltage protection (OVP), and thermal shutdown.
