Monolithic Power Systems MP5402M

5A, 36V, Frequency Selectable Step-Down Converter with Smart Dual USB Charging Ports

Overview

TopologyBuck Converter
Input voltage7-36 V
Switching frequency150-350 kHz
Output 15 V

Description

The MP5402M integrates a monolithic, step-down, switch-mode converter with two USB current-limit switches and a charging port identification circuit. It achieves 5A of continuous 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 the battery charging specification (BC1.2), the divider mode, and the 1.2V/1.2V mode, eliminating outside user interaction.The output voltage has programmable line drop compensation.Fault condition protection includes hiccup current limiting, output OVP, and thermal shutdown (TSD). The MP5402M requires a minimum number of readily available, standard, external components and is available in a QFN-26 (4mmx4mm) package.
