Output 136 V / 5 A
IC revision1.2

Description

The EVQ4214-U-00A Evaluation Board is designed to demonstrate the capabilities of MPS’ MPQ4214GU-AEC1.The MPQ4214GU-AEC1 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 MPQ4214suitable for USB power delivery (PD) design in USB Type-C power supplies.
