The EV4583-QVE-00C is an evaluation board designed to demonstrate the capabilities of the MP4583, an 8μA quiescent current (I_Q), integrated synchronous step-down converter. It supports up to 3A of output current (I_OUT) with internal compensation.

The MP4583 provides high power conversion efficiency across a wide load range, which is achieved by power-save mode (PSM) and low I_Q under light-load conditions. This reduces switching and gate driver losses. To achieve low output ripple at light loads, pull the MODE/SYNC pin high to enter forced continuous conduction mode (FCCM). The frequency is always fixed at 400kHz under all load conditions.

The MP4583 is available in a QFN-19 (3mmx5mm) package.

It is recommended to read the MP4583 datasheet prior to making any changes to the EV4583-QVE-00C.
