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.
The 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.
Figure 1. ADALM-BUCK connections and jumpers
The default jumper configurations for this board model are as follows:
|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|
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.)
