Demonstration circuit 1790A is easy to set up and evalu-
ate the performance of the LTM2886. Refer to Figure 2
for proper measurement equipment setup and follow the
procedure below.
NOTE: When measuring the input or output voltage ripple
or high speed signals, care must be taken to avoid a long
ground lead on the oscilloscope probe.
1. Install JP1 in the ON (default) position.
2. With power off, connect the input power supply to V
CC
and GND on pin header J1.
3. Turn on the power at the input.
NOTE: Make sure that the input voltage does not exceed 6V.
4. Check for the proper output voltages. V
CC2
= 5V,
V
+
= 5V, and V
–
= –5V on pin header J2.
5. Once the proper output voltages are established, con
-
nect signals to J1 and J2 pin headers as appropriate.
The header pin names and locations are detailed on the
demo board silkscreen below the pin headers.
