Quick Start Procedure - Linear Technology DC1899A Manual

QUICK START PROCEDURE

Demonstration circuit 1899A can be easily set up to evaluate
the performance of the LTC4228-1/LTC4228-2. Refer to
the Figure 1 for proper measurement equipment setup and
follow the procedure below. The DC1899A test includes
independent tests of the LTC4228 Hot Swap functionality,
ideal diode functionality and two power rails prioritizer
functionality with the channel 1 highest priority.

HOT SWAP FUNCTIONALITY TEST
This test is identical for each 12V rail and is performed
in the three steps by the measuring of the transient's
parameters in the different operation modes.
Install the jumpers in the following positions:
JP4, RON1_SEL and JP5, RON2_SEL in position OFF;
JP1, EN1_SEL and JP2, EN2_SEL in position LOW.
