Monolithic Power Systems (MPS) MP4245 Buck-Boost Converter

Monolithic Power Systems (MPS) MP4245 Buck-Boost Converter has four integrated power switches. The device can deliver up to 6A output current at specific input voltage 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 include constant current (CC) limiting, output over-voltage protection (OVP), and thermal shutdown (TSD). The Monolithic Power Systems (MPS) MP4245 requires a minimal number of readily available, standard external components and is available in a QFN-21 (4mm x 5mm) package.
