QUICK START PROCEDURE
Evaluation circuit EVAL-LT8350-AZ is easy to set up to
evaluate the performance of the LT8350. Refer to Figure 1
for proper measurement equipment setup and follow the
procedure below.
NOTE: Make sure that the voltage applied to V
IN
does
not exceed 40V, which is the voltage rating for input side
MOSFETs.
1. With power off, connect a load capable of 12V 2.5A
operation between OUT and GND turrets on the PCB
as shown in Figure 1 .
2. Connect the EN/UVLO terminal to GND with a clip-on
lead. Connect the power supply (with power off) and
meters as shown in Figure 1 .
3. Set JP1 at NO SSFM to disable SSFM, at SSFM to
enable SSFM.
4. Set JP2 at RC for typical loop compensation, at RC+FF
for load current injection scheme which improves load
transient response.
5. After all connections are made, turn on the input power
and verify that the input voltage is between 7V and 40V.
6. Remove the clip-on lead from EN/UVLO. Verify that
the output voltage is 12V.
NOTE: If the output voltage is low, temporarily discon-
nect the load to make sure that it is not set too high.
7. Once the proper output voltage is established, adjust the
input voltage and load within the operating ranges and
observe the output voltage regulation, ripple voltage,
efficiency, and other parameters.
