ADP2384-EVALZ: 3.3V @ 4A, 4.5 ~ 20V in

Summary

The ADP2384/ADP2386 evaluation board is a complete, 4 A/6 A, 20 V, step-down regulator solution that allows users to evaluate the performance of the ADP2384/ADP2386 with a near ideal printed circuit board (PCB) layout.

The switching frequency can be programmed between 200 kHz and 1.4 MHz, or it can be synchronized to an external clock with a 180° phase shift, which provides the possibility for a stackable multiphase power solution.

The output of the ADP2384/ADP2386 evaluation board is preset to 3.3 V and the switching frequency is set to 600 kHz. Different output voltage settings can be achieved by changing appropriate passive components. The ambient temperature operating range is −40°C to +85°C.
