Demonstration circuit 1817B is easy to set up to evaluate
the performance of the LT3798. Refer to Figure 1 for proper
measurement equipment setup and follow this procedure:
1. Connect an adjustable load between + and – output
2. With power off, connect the input power supply to
3. Turn on the power at the input.
NOTE. Make sure that the input voltage does not exceed
the maximum input voltage (265VAC).
4. Check for the proper output voltage.
Once the proper output voltage is established, adjust the
input voltage and/or the load and observe the output voltage
regulation, efficiency, power factor and other parameters.
