White LED 1x/1.5x Charge Pump in  
UCSP and Thin QFN  
General Description  
Features  
The MAX1573 fractional charge pump drives up to four  
white LEDs with regulated constant current for uniform  
intensity. By utilizing proprietary adaptive 1x/1.5x  
modes and ultra-low-dropout current regulators, it  
maintains the highest possible efficiency over the full  
1-cell Li+ battery input 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.  
♦ Proprietary Adaptive 1x/1.5x Modes  
♦ High Efficiency (P /P ), Up to 92%  
LEDs BATT  
♦ 0.2% LED Current Matching  
♦ 28mA/LED Drive Capability  
♦ Low Input Ripple and EMI  
♦ Eliminates Ballast Resistors  
♦ Logic or PWM Dimming Control  
♦ Low 0.1µA Shutdown Current  
♦ 2.7V to 5.5V Input Voltage Range  
♦ Soft-Start Limits Inrush Current  
♦ Output Overvoltage Protection  
♦ Thermal Shutdown Protection  
An external resistor sets the full-scale LED current, while  
two digital inputs control on/off and select amongst three  
levels of brightness. A pulse-width modulation (PWM)  
signal can also be used to modulate LED brightness,  
requiring no additional components.  
The MAX1573 is available in the tiny chip-scale UCSP™  
(4 x 4 grid) and 16-pin thin QFN packages.  
♦ No External Schottky Diode Required  
♦ Tiny UCSP (2.1mm x 2.1mm x 0.6mm) and Thin  
QFN (4mm x 4mm) Packages  
Applications  
Cell Phones, Smart Phones  
PDAs, Digital Cameras, Camcorders  
MP3 Players
