MPQ4488T

36V, 6A, Step-Down Converter with Programmable Frequency and Spread Spectrum Option, Dual USB Charging Ports, 135°C Load-Shedding Temp AEC-Q100 Qualified

Datasheet

Description

The MPQ4488T integrates a monolithic, step-down, switch-mode converter with two USB current-limit switches and charging port identification circuitry for each port. The MPQ4488T 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 (BC 1.2), divider mode, 1.2V/1.2V mode, and USB Type-C 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.

The MPQ4488T requires a minimal number of readily available, standard, external components and is available in a QFN-26 (5mmx5mm) package.
