EVALUATION KIT AVAILABLE  
Highest Efficiency Supply  
for 2 to 6 Series WLEDs in a  
2mm x 2mm TDFN Package  
MAX8901A/MAX8901B  
General Description  
Benefits and Features  
The MAX8901A/MAX8901B step-up converters drive  
from two to six series-connected white LEDs (WLEDs)  
with constant current to provide uniform WLED intensity  
for LCD backlighting in cell phones, PDAs, and other  
handheld devices. The MAX8901_ operate at a fixed  
750kHz (typ) switching frequency, allowing for tiny exter-  
nal components, and are optimized for the highest possi-  
ble efficiency over the full 1-cell Li+/Li-Poly battery range.  
• Cost-Effective and Flexible Solution for Wide Range of  
Backlighting Applications  
• Supplies from 2 to 6 WLEDs with 1.3% LED Current  
Accuracy  
• 2.6V to 5.5V Input Voltage Range  
• Fixed-Frequency Operation  
• Flexible Dimming Control  
• Direct PWM Dimming (MAX8901A)  
• 32-Step, Single-Wire Serial Dimming (MAX8901B)  
These converters use a single input (ON) to enable the  
IC and to control WLED intensity. The MAX8901A  
requires a direct PWM input to regulate WLED intensity  
with the WLED current proportional to the PWM duty  
cycle. The MAX8901B uses single-wire, serial-pulse  
dimming that reduces the WLED intensity in 32 linear  
steps. Full-scale WLED current for serial-pulse  
dimming is 24.75mA (MAX8901B, 0.75mA/step).  
• Protection Features Improve System Reliability  
• WLED Overvoltage Protection (25V typ)  
• Internal Soft-Start and Thermal Shutdown  
• Input Undervoltage Lockout  
• Input Overvoltage Lockout  
• High Efficiency Extends Battery Life  
• Up to 91% Efficiency  
The MAX8901_ feature an internal soft-start to eliminate  
inrush currents during startup, input overvoltage  
protection, WLED overvoltage protection, and a shut-  
down mode with 0.01µA (typ) shutdown current. No  
WLED current is present in shutdown provided the  
WLED forward voltage is greater than the input supply  
voltage. Additional features include undervoltage lock-  
out (UVLO) and thermal shutdown.  
• 0.01µA (typ) Shutdown Current  
• No WLED Current in Shutdown  
• 8-Pin, 2mm x 2mm TDFN Package Saves Space
