Description

The MP4245 is a buck-boost converter with four integrated power switches. The device can deliver up to 6A of output current (I_OUT) at certain input voltage (V_IN) supply ranges, with excellent load and line regulation.

The MP4245 is suitable for USB power delivery (USB PD) applications. It can work with an external USB PD controller through the I²C interface. The I²C interface and two-time programmable multiple-time programmable (MTP) memory provide flexible features.

Fault condition protections includes constant current (CC) limiting, output over-voltage protection (OVP), and thermal shutdown (TSD).

The MP4245 requires a minimal number of readily available, standard external components, and is available in a QFN-21 (4mmx5mm) package.
