The MAX16825 IC operates in linear mode. As a result,
the IC can dissipate significant power if operated using a
high input voltage and a small V
pation may cause the IC to go into thermal shutdown.
Refer to the Thermal Protection section in the MAX16824/
MAX16825 IC data sheet for more information.

The user may control the MAX16825 EV kit directly with a
user-supplied, 5V logic, 4-wire SPI interface for stand-
alone operation. Cut open header J2’s shorting traces
located on the PCB’s bottom layer. Connect the user-sup-
plied CS, SCLK, DIN, and a control signal to the OE, CLK,
DIN, and LE pads, respectively, on the MAX16825 EV kit.
Refer to the Electrical Characteristics, SPI Interface sec-
tion of the MAX16825 IC data sheet for more information
on the MAX16825’s SPI communication requirements.
