Product Description

The MPQ4488 integrates a monolithic step-down switch-mode converter with two USB current-limit switches and charging port identification circuitry for each port. It achieves 6A output current over a wide input-supply range with excellent load and line regulation. The output of the USB switch is current limited. Both USB ports support DCP schemes for Battery Charging specification (BC1.2), the Divider Mode, 1.2V/1.2V Mode and USB Type-C 5V@3A DFP Mode eliminating outside user interaction. Fault condition protection includes hiccup current limiting, output OVP, and thermal shutdown (TSD). The MPQ4488 requires a minimum number of readily available, standard, external components. The MPQ4488 is available in a QFN26 (5mmx5mm) package.

Kit details

The EVQ4483-V-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MPQ4483, which is a high-frequency, synchronous rectified, step-down, switch-mode converter. It achieves 3A output current over a wide input-supply range with excellent load and line regulation over a wide input-supply range. The MPQ4483 has synchronous-mode operation for higher efficiency over the output-load range.

MPQ4483 has CC (constant current) limit function for the output with two adjustable CC limit thresholds. MPQ4483 also supports BC 1.2 DCP mode and CDP mode.

Fault condition protection includes hiccup current limiting, OVP, Ground short to battery protection and thermal shutdown (TSD).

The MPQ4483 requires a minimum number of readily available, standard, external components. The MPQ4483 is available in a QFN25 (4mmx5mm) package.
