The MAX16806 evaluation kit (EV kit) demonstrates the
features of the MAX16806 high-current LED driver,
capable of delivering regulated current of up to a total
of 350mA to one or more strings of high-brightness
LEDs with high accuracy. This EV kit operates at supply
voltages between 5.5V to 40V and temperatures rang-
ing from 0°C to +70°C.
The MAX16806 EV kit provides a user-selectable three-
level LED current setting, connection to the 5V-regulat-
ed output, and a momentary switch to enable or disable
the dimming function. This EV kit features wide-range
dimming, controllable through a PWM input or analog
input generated using an on-board trim pot. The
MAX16806 EV kit is a fully assembled and tested PCB.
The MAX16806 EV kit provides access to the I
face of the MAX16806 IC, through which the internal
dynamic registers and the EEPROM are written/read to
control various device features. A CMAXQUSB board
can be used to enable PC communication using the I
2-wire interface. Windows
GUI software is provided to access the MAX16806 IC.
The MAX16806 EV kit can also be interfaced directly to
a user-provided I
The MAX16806 evaluation system (EV system) consists
of the MAX16806 EV kit and a companion CMAXQUSB
serial-interface board. The CMAXQUSB interface board
allows a PC to control an I
port. Order the MAX16806EVCMAXQU+ for a complete
PC-based evaluation of the MAX16806. Order the
MAX16806EVKIT+ if you already have a CMAXQUSB
interface board, or if you have your I
not require PC-based evaluation of the MAX16806.
19-0682; Rev 3; 11/08
+ Denotes lead-free and RoHS compliant.
Note: The MAX16806 EV kit software is included with the
MAX16806 EV kit, but is designed for use with the complete EV
system. The EV system includes both the Maxim CMAXQUSB+
interface board and the EV kit. If the evaluation software will
not be used, the EV kit board can be purchased without the
Maxim CMAXQUSB+ board.
