Test Equipment
DC Voltage Source: Capable of supplying the input of the EVM up to 480 V
DC Bias Source: Capable of 12 V output at up to 0.7 A
Function Generator: Capable of 0 V to 5 V square wave output with adjustable duty cycle and frequency in
desired operating range. It is recommended to operate the LMG3411EVM-029 and LMG34XX-BB-EVM
with a switching frequency between 50 kHz to 200 kHz.
Oscilloscope: Capable of at least 200 MHz operation. A 1 GHz or greater oscilloscope and probes with
short ground springs are recommended for accurate measurements.
DC Multimeter(s): Capable of 600 V measurement, suitable for determining operation and efficiency (if
desired).
DC Load: Capable of 600 V operation at up to 8 A in current-mode operation.
Fan: 200 LFM minimum airflow is recommended.
