Quick start proceDure

DC2072A is easy to set up to evaluate the performance of
the LT3065. Refer to Figure 1 for the proper measurement
equipment setup and follow the procedure below:
NOTE: Make sure that the input voltage does not exceed 45V.
NOTE: The shutdown jumper JP2 shunt is required to be
placed in the OFF or ON position for proper operation.
NOTE: Place the output voltage selection jumper JP1 at
the desired position.
NOTE: Do not hot-plug the input voltage terminal V
absolute maximum voltage on V
a power supply through wire leads to the demonstration
circuit can cause the voltage on the extremely low-ESR
ceramic input capacitor to ring to twice its DC value. In
order to protect the IC, a higher ESR Aluminum Electro-
lytic capacitor is placed at the input terminals. This may
protect against some, but not all, input transients due to
hot-plugging with a power supply. See Application Note
88 for more details.

NOTE: Connect the power supply (with power off), load,
and meters as shown in Figure 1.
1. After all connections are made, turn on input power and
verify that the output voltage according to the output
voltage selection jumper JP1. If the output voltage is
different from the above values, use the USER option
and install R8. Select R8 according to the following
equation:
R8 = (V /0.6-1) • 60.4k
OUT
NOTE: If the output voltage is too low, temporarily
disconnect the load to make sure that the load is not
set too high.
2. Once the proper output voltage is established, adjust the
load within the operating range and observe the output
voltage regulation, PWRGD and other parameters.
