8.2 Start-Up and Operating Procedure

The following procedure is recommended to enable the LMG342XEVM-04X with the LMG342XEVM-04X:

  1. Power up the 12-V bias supply. Ensure the top right green “Aux Enable” LED is illuminated.
  2. Enable PWM on the function generator.
  3. Power up the high voltage input supply. Ensure the red “HV Enable” LED is illuminated when the input supply is above 20 V.
WARNING:

Do NOT turn on device at absolute maximum voltage. TI recommends starting at voltages at or below 480 V, and then increase the input voltage slowly while monitoring VSW to insure the peak voltage does not exceed the absolute maximum rating of 600 V.
