DEMO MANUAL DC1601B
Figure 1
Demonstration circuit DC1601B is easy to set up to evaluate
the performance of paralleled LTM4607 modules. Please
refer to Figure 1 for proper measurement equipment setup
and follow the procedure below:
1. With power off, connect the input power supply, load,
and meters as shown in Figure 1. Preset the load to 0A
and V
IN
supply to be 0V. Place jumpers in the following
positions for a typical 12V

2. Turn on the power at the input. Increase V
IN
to 18V
(Do not hot-plug the input supply or apply more than
the rated maximum voltage of 36V to the board or the
modules may be damaged).
3. Set the run pin jumper (JP1) to the ON position. The
output voltage should be regulated. The output voltage
meter should read 12V ±2% (11.76V to 12.24V).
4. Vary the input voltage from 6V to 36V and adjust the
load current from 0A to 10A (for DC1601B-A), 0A to
15A (for DC1601B-B), 0A to 20A (for DC1601B-C).
V
OUT
should remain regulated at 12V ±2% (11.76V to
12.24V). Observe the load regulation, efficiency and
other parameters.
5. Set the load current to 0A. Set the RUN pin jumper
(JP1) to the OFF position. Turn off input supply before
disconnecting the circuit.
