MPQ4272 integrates dual-channel, monolithic step-down converters with an I2C interface. Each channel can deliver up to 3A of output current across a wide input supply range, with excellent load and line regulation. The MPQ4272 is designed for USB charger applications with dual ports. Both channels can work with an external USB power deliver (PD) controller. The I2C interface and one-time programmable (OTP) memory provide flexibility with configurable features. Fault condition protections include current limiting, output over-voltage protection (OVP), and thermal shutdown (TSD). The MPQ4272 requires a minimal number of readily available, standard external components. It is available in a QFN-21 (4mmx5mm) package.
