Evaluation Board for the ADP2384/ADP2386, 20 V, 4 A/6 A Synchronous Step-Down

DC-to-DC Regulators

FEATURES

GENERAL DESCRIPTION

The ADP2384/ADP2386 evaluation board is a complete, 4 A/6 A,

20 V, step-down regulator solution that allowsusers to evaluate the

performance of the ADP2384/ADP2386 with a near ideal printed

circuit board (PCB) layout.

Input voltage: 4.5 V to 20 V

1% output voltage accuracy

Integrated MOSFET

44 mΩ/11 mΩ

Continuous outputcurrent

4 A for ADP2384

6 A for ADP2386

Programmable switching frequency: 200 kHz to 1.4 MHz

Synchronizes to external clock: 200 kHz to 1.4 MHz

180° out-of-phase synchronization

Precision enable and power good

External compensation

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.

Internal soft start with external adjustable option

Startup into precharged output

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.
