5.3.6 Bench Setup Diagram
The current bench setup diagram includes the function generator and oscilloscope connections.
Use the following connection procedure and also use Figure 5-2 as a reference:
• Make sure all the output of the function generator, voltage source are disabled before connection;
• Function generator channel-A channel applied on INA (TP3) ←→ GND (TP14) as seen in
Figure 5-2 ;
• Function generator channel-B channel applied on INB (TP5) ←→ GND (TP6) as seen in Figure 5-2 . For
the UCC20520EVM, INB, J-INB and TP15 are not installed because the UCC20520 is a single PWM input,
dual-channel output Iso-Driver;
• Power supply #1: positive node applied on VCCI (TP1), and negative node applied on GND (TP2);
• Power supply #2: positive node connected to input of DMM #1 and DMM #1 output connected to VDDA
(TP17), negative node connected directly to VSSA (TP19);
• Power supply #3: positive node connected to input of DMM #2 and DMM #2 output connected to VDDB
(TP20), negative node connected directly to VSSB (TP22);
• Oscilloscope channel-A probes TP14, smaller measurement loop is preferred;
• Oscilloscope channel-B probes TP16, smaller measurement loop is preferred;
