EVQ4571-QB-00A

The EVQ4571-QB-00A is an evaluation board designed to demonstrate the capabilities of the MPQ4571 and MPQ4571-AEC1.

The MPQ4571 is a fully integrated, fixed-frequency, synchronous step-down converter. It can achieve up to 1A of continuous output current (I_OUT) with peak current control for excellent transient response.

The MPQ4571 employs  advanced asynchronous modulation (AAM) mode to achieve high efficiency under light-load conditions by scaling down the switching frequency (f_SW). This reduces switching and gate driving losses.

The EVQ4571-QB-00A is a fully assembled and tested evaluation board that can generate a 5V output voltage (V_OUT) at load currents up to 1A from a 5V to 60V input voltage (V_IN) range.
