Evaluates: MAX1739 19-2114 Rev 0 7/01 MAX1739 Evaluation System/ Evaluation Kit General Description Features The MAX1739 evaluation system (EV system) consists Wide Brightness Adjustment Range of a MAX1739 evaluation kit (EV kit) and a companion Open Lamp Protection with 2s Timeout Maxim SMBus interface board. Buck Switch and Other Single-Point Fault The MAX1739 EV kit is an assembled and tested PC board that demonstrates the MAX1739 wide brightness Protection range cold-cathode fluorescent lamp (CCFL) backlight Brightness Adjustable Through SMBus Interface controller. The EV kit can control the brightness of a or On-Board Potentiometer user-supplied lamp through either the SMBus interface or by an on-board potentiometer. Figure 1 shows the No Flicker at Low Brightness MAX1739 EV kit main display. High Power to Light Efficiency The Maxim SMBus interface board (MAXSMBUS) allows 2 I C/SMBus Compatible an IBM-compatible PC to use its parallel port to emulate an Intel system management bus (SMBus) 2-wire inter- Easy-to-Use Menu-Driven Software face. Windows 95/98 -compatible software provides a Assembled and Tested user-friendly interface to exercise the features of the MAX1739. The program is menu driven and offers a Includes: Windows 95/98-Compatible Software graphic interface with control buttons and status display.
