4 / 14 page  4 dc2374afa DEMO MANUAL DC2374A 24V SUPPLY QUICK START PROCEDURE The DC2374A 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 VIN or VOUT and GND terminals. See Figure 2 for proper scope probe technique. 1. Set the DC2374A 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 JP4 MODE1 – HI JP5 NTC – INT JP6 TIMER – CAP JP7 PULL_UP PWR - DCIN 2. With power off, connect a 0V to 16V, 6A power supply (PS2) to BAT and GND terminals with a series ammeter 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. CHARGING OPTIONS Table 1.
