MPQ4214
Overview
The MPQ4214 is a synchronous, four-switch, buck-boost controller capable of regulating different output voltages with a wide input voltage range and high efficiency. The MPQ4214 provides an I2C interface, which supports VOUT voltage programmability, VOUT slew-rate control, and constant output current limit programmability, making the MPQ4214 suitable for USB power delivery (PD) design in USB Type-C power supplies.
