4.1Connect one lead from the “+” lead of the DC source (See Item 3.1) to the “20A” terminal of the first multi-meter DVM1 (See Item 3.3). Then connect one lead from the “Common” of the DVM1 to the “Vin” pin of the Evaluation Board. DVM1 is used to measure the input current.

4.2Connect one wire from the “-” lead of the DC source (See Item 3.1) to the “GND“ pin of the Evaluation Board. Note: Use stranded leads at least equivalent to 14 AWG for all connections in sections 4.1 and 4.2. The leads should be twisted to reduce noise coupling.

4.3Connect the plus “+” and minus “-“ connection leads from a second multi-meter (See Item 3.3) to the “SVin” and “SGND” pins on the Evaluation Board. This multi-meter is designated DVM2. DVM2 is used to measure the input voltage.

4.4Connect the plus “+” and minus “-“ connection leads from the third multi-meter (See Item 3.3) to the “SVOUT” and “SGND” Pin on the Evaluation Board. The multi-meter is designated DVM3. DVM3 is used to measure the output voltage.

4.5Connect a BNC cable (length less than 20 inches/500mm) from BNC1 of the Evaluation Board to Channel 1 of the oscilloscope (See Item 3.2). This cable is used to measure the input voltage (between SVIN and SGND).

4.6Connect a BNC cable (length less than 20 inches/500mm) from BNC2 of the Evaluation Board to Channel 2 of the oscilloscope (See Item 3.2). This cable is used to measure the output voltage (between SVOUT and SGND).

4.7Connect the positive and negative power leads of the electronic load (ensuring correct polarity), or an appropriate resistive load to the Evaluation Board output terminal pin (“Vout” for positive power lead and “SGND” for the negative power lead).

4.8Connect one lead from the “+” lead of the DC source (See Item 3.5) to the “12Vcc” on the Evaluation Board. Then connect one lead from the “-” of the DC source (See Item 3.5) to the “12VGND” on the Evaluation Board.

5.0Thermal Management of the Converter

It is imperative that sufficient airflow needs to be provided to the converter at all times during all portions of testing. Please refer to the applicable data sheet for the proper cooling and derating necessary conditions to obtain accurate results when testing the converter.
