SC604A  
Low Noise, High Efficiency  
Regulated White LED Driver  
POWER MANAGEMENT  
OBJECTIVE -NOVEMBER  
Description  
Features  
9, 2000  
The SC604A is a very high efficiency charge pump white Very high efficiency over 90% of battery life  
LED driver driver from the mAhXLifeTM family of products,  
optimized for Li-Ion battery applications.  
Peak efficiency over 92%  
Current regulation for up to 4 LEDs  
Digital 3 bit output control logic  
Current matching tolerance of ±3% typical  
Wide current range per LED [0.5mA - 30mA]  
High available total LED current = 4 ILED = 120mA  
Low Shutdown Current: 1µA typical  
Soft start / In-rush current limiting  
Short circuit protection  
MLP-16 [4x4] Package  
Fixed frequency 250kHz  
The four (4) LED outputs are current matched for consis-  
tent LED brightness. Extremely low battery current is  
achieved by automatically reconfiguring the charge pump  
to match circuit conditions. Using four LEDs, each at  
20mA for a total IOUT= 80mA, the SC604A can use less  
than 83mA from the supply for most of the battery life.  
Patented low noise mode switching circuitry and constant 1x, 1.5x and 2x charge pump modes of operation  
output current allow the use of extremely small input and  
output capacitors.  
Applications  
Cellular phones Electronic books  
LED backlighting Wireless web appliances  
PDA power supplies LCD Modules
