Ultra-Efficient Charge Pumps for  
Six White/RGB LEDs in 3mm x 3mm Thin QFN  
7/MAX648  
General Description  
Features  
♦ Six Adaptive Current Regulators  
The MAX8647/MAX8648 drive up to six white LEDs or  
two sets of RGB LEDs with regulated constant current  
for display backlight and fun light applications. By utiliz-  
ing an inverting charge pump and extremely low-  
dropout adaptive current regulators, these ICs achieve  
very high efficiency over the full 1-cell Li+ battery volt-  
age range and even with large LED forward voltage  
mismatch. The 1MHz fixed-frequency switching allows  
for tiny external components. The regulation scheme is  
optimized to ensure low EMI and low input ripple. The  
MAX8647/MAX8648 include thermal shutdown, open-  
and short-circuit protection.  
♦ Independent Voltage Supply for Each LED  
♦ Individual LED Brightness Control (MAX8647)  
♦ 24mA to 0.1mA Dimming Range

♦ Inrush Current Limit  
♦ T Derating Function Protects LEDs  
♦ 16-Pin, 3mm x 3mm Thin QFN Package

The MAX8647 features an I C serial port, while the  
MAX8648 features a three-wire serial-pulse logic inter-  
face. Both devices support independent on/off and  
dimming for main and subbacklights. The dimming  
ranges are pseudo-logarithmic from 24mA to 0.1mA  
and off in 32 steps. Both devices include a temperature  
derating function to safely allow bright 24mA full-scale  
output current setting while automatically reducing cur-  
rent to protect LEDs at high ambient temperatures  
above +60°C.
