Analog Devices Inc. EVAL-ADP2387 EvalBoard for ADP2387 DC/DC Regulator

Analog Devices EVAL-ADP2387 Evaluation Board provides a complete 20V, 6A, step-down regulator solution that allows designers to evaluate the ADP2387 in a near-ideal printed circuit board (PCB) layout. The board's programmable current-limit function allows the output current to optimize the inductor. A preset 9A peak current-limit threshold ensures the 6A output current capability. Designers can program the switching frequency between 200kHz and 1.4MHz, which provides the possibility for a stackable multiphase power solution. The output of the ADP2387-EVALZ evaluation board is preset to 3.3V, and the switching frequency is set to 600kHz. Different output voltage settings can be used by changing the appropriate passive components.
