MP4245 is a buck-boost converter with four integrated power switches. The device can deliver up to 6A of output current at certain 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 includes constant current (CC) limiting, output overvoltage 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. Applications include USB Type-C with PD charging only ports, 12V bus voltage supplies and wireless charging.
