EVQ5472-Q-00A

The EVQ5472-Q-00A is an evaluation board designed to demonstrate the capabilities of the MPQ5472-AEC1, 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 DC/DC converters provide constant-on-time (COT) control for fast transient response. The configurable 500kHz to 1.25MHz switching frequency (f_SW) significantly reduces external inductor and capacitor size. Full protection features include 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 preset by the multiple-time programmable (MTP) memory function. The start-up/shutdown sequence and delay can be configured via the MTP, or they can be controlled via the I²C bus online.

The two rails can be configured to work in independent mode or parallel mode. Current balancing is implemented when operating in parallel mode. It is recommended to read the MPQ5472 datasheet prior to making any changes to the EVQ5472-Q-00A.
