GENERAL DESCRIPTION
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.
Full details on the ADP2384 and ADP2386 regulators are
provided in the ADP2384 and ADP2386 data sheets, available
from Analog Devices, Inc., which should be consulted in
conjunction with this user guide.
