-====== ADALM-BUCK-ARDZ ====== +
- +
-===== Description===== +
- +
-The ADALM-BUCK-ARDZ is base from [[https://www.analog.com/en/products/lt1054.html|LT1054]] which is a monolithic, bipolar, switched-capacitor +
-voltage converter and regulator. This allows for students to analyze its functionality as well as the performance of the circuit using a controlled evaluation environment.  +

 +===== 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.) 
  
-===== ADALM-BUCK-ARDZ Power Rails ===== +{{ :university:tools:lab_hw:adalm_buck:adalm-buck_m2k_connections.jpg?direct&600 |}}
- +
-EVAL-M355-ARDZ-INT provides 2.5V votlage output from a 5V USB power supply with 5mA maximum power consumption. +
- +
-===== Hardware Setup Procedure =====+
  
-If you are using the ADICUP3029 development board with the EVAL-M355-ARDZ-INT adaptor board, please use the following setup procedure: +<WRAP centeralign> Figure 2. ADALM-BUCK - ADALM2000 connections</WRAP>
  
-  - Connect the 5 V USB power supply to P25 (EXT PWR) using the USB-A to micro-USB cable. 
-  - Set the multimeter to measure voltage and connect its leads to TP2 (+) and TP1 (-) as shown below: 
-{{ :resources:eval:user-guides:circuits-from-the-lab:adalm-buck-ardz:test_setup.jpg?400 |}} 
-<note>With the default jumper settings, the measured the DC voltage across TP2 and TP1 will be around 2.5V.</note>
