DEMO MANUAL DC1674A-A

Figure 1. Proper Measurement Equipment Setup

DC1674A-A working input voltage range is 4.35V to 5.5V

on both the WALL and USB input. The DC1674A-A will

tolerate non-operating overvoltage inputs up to 27V.

board, to control the LTC4155EUFD and to read back the

contents of the command and status registers.

The DC1674A-A is easy to set up to evaluate the perfor-

mance of the LTC4155EUFD. Refer to Figure1 andFigure 2

for proper measurement equipment setup and follow the

evaluation procedure below using the DC590B board.

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

probe technique.
