MP5475

Fully Integrated, 12V, 6A, Quad-Buck PMIC with I²C, Telemetry, and Flexible System Configurations

Datasheet

Description

The MP5475 is a complete power management IC (PMIC) that integrates four high-efficiency step-down DC/DC converters and a flexible logic interface.

The integrated DC/DC converters provide constant-on-time (COT) control to achieve fast transient response. In addition, the 1MHz switching frequency (f_SW) minimizes the external inductor and capacitor size. Full protection features include under-voltage lockout (UVLO), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown.

The output voltage (V_OUTx) (where x = A, B, C, or D) can be adjusted via the I²C bus, or it can be preset by the multiple-time programmable (MTP) memory function. The power on/off sequence can also be configured by the MTP, or it can be controlled online via the I²C.

The first two rails or the last two rails can work in either independent mode or parallel mode, which can be configured via the MTP. The current-sharing function is implemented in parallel mode.

The MP5475 requires a minimal number of external components, and it is available in a space-saving QFN-35 (5mmx5mm) package.
