Description

MPL

Optimized Performance with MPS Inductor

The MP5472 is a complete power management IC (PMIC) that integrates two high-efficiency, step-down DC/DC converters, one adjustable output low-dropout (LDO) regulator, and a flexible logic interface.

The integrated DC/DC converters provide constant-on-time (COT) control for fast transient response. The configurable 500kHz to 1.25MHz 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 = 1 or 2) can be adjusted via the I²C bus, or it can be preset by the multiple-time programmable (MTP) memory. The start-up/shutdown sequence can also be configured by the MTP, or it can be controlled online via the I²C.

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

The MP5472 requires a minimal number of external components, and is available in a space-saving QFN-26 (4mmx4mm) package.

Optimized Performance with MPS Inductor

The EVL5472-Q-00A evaluation board is designed to demonstrate the capabilities of the MP5472, a complete power management IC (PMIC) that integrates two highly efficient stepdown DC/DC converters, one adjustable-output low-dropout (LDO) regulator, and flexible logic interface.

The MP5472 adopts constant-on-time (COT) control, and the DC/DC converters provide fast transient response. A configurable 500kHz to 1.25MHz switching frequency (f_SW) greatly reduces external capacitance.

Full protection features include under-voltage lockout (UVLO), over-current protection (OCP), under-voltage protection (UVP), over-voltage protection (OVP), and thermal shutdown.

The output voltage (V_OUT) is adjustable via the I²C bus, or can be preset uding the multiple-time programmable (MTP) memory. The power-on and power-off sequence and delay are configurable via the MTP or can be controlled via the I²C bus.

The two rails can be configured to work in either independent mode or parallel mode. Current-sharing is implemented when working in parallel mode.

The MP5472 requires a minimal number of external components, and is available in a space-saving QFN-26 (4mmx4mm) package. It is recommended to read the MP5472 datasheet prior to making any changes to the EVL5472-Q-00A.
