ADALM-BUCK-ARDZ
Overview
The ADALM-BUCK-ARDZ board is a companion module for the Buck Basics lab exercise: Activity: Buck Converter Basics
This lab exercise can be done on a breadboard using parts from the ADALP2000 parts kit, but it is too involved to do in a hands-on seminar session or single-day workshop. The ADALM-BUCK-ARDZ module is designed to eliminate the assembly time associated with constructing the circuit on a breadboard, while keeping all of the measurements and experiments intact.
Figure 1 shows the various connections, and along with the schematic below can be used as a guide as you work through the lab exercise.

ADALM-BUCK-ARDZ Jumpers and Connections
The default jumper configurations for this board model are as follows:
| Jumper | Function | Default Setting |
|---|---|---|
| P1 | Power Supply Select | Shunt installed across pins 2 & 3 (5V from Arduino) |
| P2 | Inductor Tap # | Shunt installed across pins 1 & 2 (6 taps/max inductance) |
| P3 | Inductor Voltage | Open (for M2K connection) |
| P5 | DC coupling (remove for AC coupling) | Shunt installed |
| P6 | Output at pin 1, lower 2 pins are GND | Open (for M2K connection) |
| P10 | Arduino Analog input 0 | Solder Blobbed |
| P13 | Override source | Shunt installed across pins 1 & 2 (Arduino PWM) |
| P17 | Enable Override | Shunt NOT installed |
| P18 | Switch Node at pin 1, lower 2 pins are GND | Open (for M2K connection) |
| P19 | 10μF output capacitor | Shunt installed |
| P20 | 47μF output capacitor | Shunt installed |
| P24 | Arduino PWM output 3 | Solder Blobbed |
| All Others | Open / no shunt installed | |
Hardware Setup Procedure
Figure 2 shows the ADALM2000 connections for measuring the switch node voltage on Channel 1 and ripple current on Channel 2. The ADALM-BUCK is installed on an Arduino UNO clone with LT1054_voltage_mode_buck_DC_ctrl.ino sketch uploaded (refer to Buck Basics lab exercise for details.)
