Figure 1. DC1161B Proper Equipment Setup
Figure 2. Measuring Input or Output Ripple
Demo circuit 1161B is easy to set up to evaluate the
performance of the LT3507. Refer to Figure 1 for proper
measurement equipment setup and follow the procedure
below:
Note: When measuring the input or output voltage ripple,
care must be taken to avoid a long ground lead on the
oscilloscope probe. Measure the input or output voltage
ripple by touching the probe tip directly across the VIN or
VOUT and GND terminals. See Figure 2 for proper scope
probe technique.
1. With power off, connect the input power supply to VIN
and GND.
2. Turn on the power at the input.
Note: Make sure that the input voltage does not exceed 36V.
3. Check for the proper output voltages.
Note: If there is no output, temporarily disconnect the load
to make sure that the load is not set too high.
4. Once the proper output voltages are established, adjust
the load within the operating range and observe the
output voltage regulation, ripple voltage, efficiency and
other parameters.
