MPQ4230

MPQ4230

36V, 6A Peak, Buck-Boost Converter with I²C Interface for Automotive Power Delivery, AEC-Q100

Description

The MPQ4230 is a buck-boost converter with four integrated power switches. The device can deliver up to 5A of output current within a certain input-supply range with excellent load and line regulation.

The MPQ4230 is designed for USB power delivery (USB PD) application. It can work well with external USB PD controller through an I²C interface. The I²C interface and MTP (2-time programmable) provide flexibility of configurable features.

Fault condition protections include CC current limiting, output OVP, and thermal shutdown (TSD). The MPQ4230 requires a minimal number of readily available, standard external components. The MPQ4230 is available in a QFN-21 (4mmx5mm) package.
