DEMO MANUAL DC1506A
QUICK START PROCEDURE
Demonstration circuit description 1506A is easy to set
up to evaluate the performance of the LTC4361. Refer to
Figure 2 and Figure 3 for proper measurement equipment
setup and follow the procedure below.
1. Connect a power supply across V
IN
and GND.
2. Select ENABLE at JP2 to enable the protection.
3. Select protection type at JP1 and connect a load and
voltmeter across the corresponding output and GND:
a. For overvoltage and overcurrent protection select
(A) OV/OC and connect to OUT(A). Figure 2a.
b. For overvoltage, overcurrent and negative voltage
protection select (B) OV/OC/NV and connect to
OUT(B). Figure 2b.
c. For overvoltage, overcurrent, negative voltage,
and reverse current protection select (C) OV/OC/
NV/RC, connect to OUT(C). Figure 2c.
4. For USB protection, connect a USB cable from J2 to
the USB device (Figure 3). Select the protection type
at JP1 and match JP3 to JP1. Connect a second USB
cable from a computer to J1.
