from the Action menu bar. The Maxim Command
Module Interface window pops up (Figure 2) and
includes a 2-wire interface tab that allows for execu-
tion of simple I
2
C/SMBus commands.
The SMBus edit boxes in the Command (SMBus
Protocols, Raw Block Read/Write, EEPROM
Read/Write) group box accept numeric data in binary,
decimal, or hexadecimal. Hexadecimal numbers should
be prefixed by $ or 0x. Binary numbers must be exactly
eight digits. See Figure 2 for an illustration of this tool.
Detailed Description of Hardware
The MAX17061 EV system (MAX17061EVCMAXQU+)
consists of the MAX17061 EV kit (MAX17061EVKIT+)
and the Maxim CMAXQUSB+ command module. The
EV kit evaluates the MAX17061 WLED driver and the
CMAXQUSB provides the I
2
C/SMBus-compatible inter-
face for software control of the LED brightness in 256
steps, backlight-controller operating mode, manufactur-
er and silicon revision detection, and fault detection.
The MAX17061 EV kit can be operated in single- (V
IN
=
7V to 21V) or dual-supply (V
IN
= 7V to 21V, V
CC
= 4.5V
to 5.5V) mode through selection of jumper JU10. LED
current can be configured to provide a fixed 25mA or
adjustable 15mA to 30mA full-scale LED current
through jumper JU11 and/or resistor R5.
The MAX17061 EV kit utilizes a step-up DC-DC convert-
er to generate the voltage required to drive up to eight
strings of 10 surface-mount WLEDs. As shipped, the
MAX17061 EV kit is configured for evaluation with four
strings of 10 WLEDs.
