DEMO MANUAL DC2504A

QUICK START PROCEDURE

Demonstration circuit 2504A is easy to set up to evalu-

ate the performance of the LT8630. Refer to Figure 5 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 5 for

the proper scope technique.

1. With power off, connect the input power supply to VIN

and GND. If the EMI/EMC performance is required, the

input EMI filter should be installed, and input power

supply should be connected to VEMI and GND.

2. With power off, connect loads from VOUT to GND.

3. Turn on the power at the input.

Make sure that the input voltage does not exceed 100V.

4. Check for the proper output voltages (VOUT = 12V).

Note. If there is no output, temporarily disconnect the

load to make sure that the load is not set too high or

is shorted.

5. Once the proper output voltage is established, adjust

the load within the operating ranges and observe the

output voltage regulation, ripple voltage, efficiency and

other parameters.
