MPS发布最新BUCK-BOOST电源芯片MP4245支持40V输入 6A输出电流

MP4245 支持36V, 6A Peak, Buck-Boost Converter with I2C Interface for Power Delivery

The MP4245 is a Buck-Boost converter with 4 integrated power switches. The device can deliver up to 6A output current at certain input-supply range with excellent load and line regulation.

The MP4245 is suitable for USB power delivery (USB PD) application. It can work well with external USB PD controller through I2C interface.

The I2C interface and MTP (2 times programmable) provide flexibility of programmable features.

Fault condition protection includes CC current limiting, output OVP, and thermal shutdown (TSD).

The MP4245 requires a minimum number of readily available, standard, external components. The MP4245 is available in a QFN21 (4mmx5mm) package.
