General Description
The CS5466 is a low cost power/energy IC with pulse
output for power measurement solutions. The
CDB5466U Evaluation Board is an inexpensive tool
designed to evaluate the functionality and perfor-
mance of the CS5466.
The evaluation board is designed to output energy-to-
pulse conversions upon power-up. The CS5466 data
sheet should be read and consulted when using the
CDB5466U evaluation board.
The evaluation board includes a microcontroller with a
USB interface. The microcontroller and GUI (Graphi-
cal User Interface) provide a means to quickly register
and evaluate the CS5466’s energy-to-pulse outputs.
