MAX1739 Evaluation System/
Evaluation Kit
General Description
The MAX1739 evaluation system (EV system) consists
of a MAX1739 evaluation kit (EV kit) and a companion
Maxim SMBus鈩?interface board.
The MAX1739 EV kit is an assembled and tested PC
board that demonstrates the MAX1739 wide brightness
range cold-cathode fluorescent lamp (CCFL) backlight
controller. The EV kit can control the brightness of a
user-supplied lamp through either the SMBus interface
or by an on-board potentiometer. Figure 1 shows the
MAX1739 EV kit main display.
The Maxim SMBus interface board (MAXSMBUS) allows
an IBM-compatible PC to use its parallel port to emulate
an Intel system management bus (SMBus) 2-wire inter-
face. Windows 95/98
廬
-compatible software provides a
user-friendly interface to exercise the features of the
MAX1739. The program is menu driven and offers a
graphic interface with control buttons and status display.
Order the MAX1739EVSYS for a complete PC-based
evaluation of the MAX1739. Order the MAX1739EVKIT if
you already have an SMBus interface.
