EVL5475-U-00B

Fully Integrated, 12V, 6A, Quad-Buck PMIC with I²C Evaluation Board

Datasheet

Description

The EVL5475-U-00B is an evaluation board designed to demonstrate the capabilities of the MP5475, a complete power management IC (PMIC) that integrates four high-efficiency, step-down DC/DC converters and a flexible logic interface.

The MP5475 adopts constant-on-time (COT) control. The device’s DC/DC converter also provides fast transient response and facilitates loop stabilization. Full protection features include under-voltage lockout (UVLO), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown. Refer to the MP5475 datasheet for more detailed information.

It is recommended to read the MP5475 datasheet prior to making any changes to the EVL5475-U-00B.
