1x/1.5x/2x White LED Charge Pumps with  
Two LDOs in 4mm x 4mm TQFN  
General Description  
Features  
The MAX8645X/MAX8645Y charge pumps drive up to  
eight white LEDs with regulated constant current for uni-  
form intensity. The main group of LEDs (M1–M6) can be  
driven up to 30mA per LED for backlighting. The flash  
group of LEDs (F1 and F2) is independently controlled  
and can be driven up to 200mA per LED (or 400mA total).  
Two 200mA LDOs are on-board to provide power for  
camera functions. The LDOs’ output voltages are pin pro-  
grammable to meet different camera-module require-  
ments. The MAX8645X and MAX8645Y differ only in LDO  
output voltages. By utilizing adaptive 1x/1.5x/2x charge-  
pump modes and very-low-dropout current regulators,  
the MAX8645X/MAX8645Y achieve high efficiency over  
the full 1-cell lithium-battery voltage range. The 1MHz  
fixed-frequency switching allows for tiny external compo-  
nents, and the regulation scheme is optimized to ensure  
low EMI and low input ripple.  
♦ Power Up to Eight LEDs  
Up to 30mA/LED Drive for Backlight  
Up to 400mA Total Drive for Flash  
♦ Two Internal Low-Noise 200mA LDOs  
♦ 94% Max/85% Avg Efficiency (P

) over Li+  
LED BATT  
Battery Discharge  
♦ 0.2% Typical LED Current Matching  
♦ Adaptive 1x/1.5x/2x Mode Switchover  
♦ Flexible Brightness Control  
Single-Wire, Serial-Pulse Interface (32 Steps)  
2-Bit Logic (Three Levels)  
♦ Thermal T Derating Function  
A
The MAX8645X/MAX8645Y are available in a 28-pin TQFN,  
4mm x 4mm (0.8mm max height) lead-free package.  
♦ Low Input Ripple and EMI  
♦ 2.7V to 5.5V Supply Voltage Range  
Applications  
Camera Phones and Smartphones  
Backlighting and Flash  
♦ Soft-Start, Overvoltage, and Thermal-Shutdown
