MAX6948 Evaluation Kit  
Evluates:MAX6948B  
General Description  
Features  
The MAX6948 evaluation kit (EV kit) provides a proven  
design to evaluate the MAX6948B 5-port, constant-  
current LED driver with PWM intensity control and inte-  
grated boost converter in a 25-bump WLP package.  
o 2.7V to 5V V+ Supply Range  
o Boost Converter Drives 6 Series White LEDs  
o Boost Output PWM Dimming  
®
The EV kit also includes Windows 2000-, Windows  
o Selectable Current Sinks for LEDs  
®
®
XP -, and Windows Vista -compatible software that  
provides a simple graphical user interface (GUI) for  
exercising the features of the MAX6948B. The  
MAX6948 EV kit PCB comes with a MAX6948BGWA+  
installed.  
o Windows 2000-, Windows XP-, and Windows Vista  
(32-Bit)-Compatible Software  
o USB-PC Connection (Cable Included)  
o Proven PCB Layout  
The MAX6948 EV kit boost converter drives 6 high-  
brightness white LEDs in series with 30mA (typ). The  
boost converter features 10-bit PWM dimming, standby  
mode, input current limit, and overvoltage protection.  
o Fully Assembled and Tested  
Ordering Information  
The MAX6948 EV kit’s I/O ports drive LEDs or act as  
open-drain GPIO port expanders. Jumpers easily  
switch between the two functions. The ports feature  
selectable constant-current sinking, fading, and 8-bit  
PWM.
