24V SUPPLY QUICK START PROCEDURE
The DC2374B is easy to set up to evaluate the performance
of the LTC4013. Refer to Figure 1 and Figure 2 for proper
measurement equipment setup.
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 V
V and GND terminals. See Figure 2 for proper scope
OUT
probe technique.
1. Set the DC2374B to operate in a three stage lead acid
battery charging mode by positioning the jumpers as
listed below:
JP1 ENABLE - UVLO
JP2 MPPT - OFF
JP3 MODE2 – LO

2. With power off, connect a 0V to 16V, 6A power supply
or
(PS2) to BAT and GND terminals with a series ammeter
IN
and a voltmeter as shown in Figure 1.
3. With power off, connect a 5.1A load (LOAD1) to BAT
and GND terminals in parallel with PS2 as shown in
Figure 1.
4. Set PS2 to 10V and turn on PS2 and LOAD1.
5. With power off, connect a 0V to 35V, 5A power supply
(PS1) to DCIN and GND terminals with a series am-
meter and a voltmeter as shown in Figure 1.
