White LED 1x/1.5x Charge Pump  
for Main and Sub-Displays  
General Description  
Features  
The MAX1575 charge pump drives up to four white  
LEDs in the main display and up to two white LEDs in  
the sub-display with regulated constant current for uni-  
form intensity. By utilizing adaptive 1x/1.5x charge-  
pump modes and very-low-dropout current regulators,  
it achieves high efficiency over the full 1-cell lithium-  
battery input voltage range. A 1MHz fixed-frequency  
switching allows for tiny external components, and the  
regulation scheme is optimized to ensure low EMI and  
low input ripple.  
♦ Powers Main and Sub-Display LEDs  
♦ 85% Average Efficiency (P  
Battery Discharge  
/ P  
) Over Li+  
BATT  
LED  
♦ 2% LED Current Matching  
♦ Up to 30mA/LED Drive Capability  
♦ Adaptive 1x/1.5x Mode Switchover  
♦ Low Input Ripple and EMI  
♦ Individual 5% to 100% Dimming Through  
Single-Wire Serial Pulse Interface  
♦ Low 0.1µA Shutdown Current  
The MAX1575 uses an external resistor to set the full-  
scale 100% LED current. Two enable inputs, ENM and  
ENS, are used for simple on/off controls for the main and  
sub-displays, respectively. By repeatedly pulsing either  
enable input, the LEDs can be dimmed in multiple steps  
down to 5%. Once the desired brightness is set, the  
MAX1575 maintains that brightness setting as long as  
the enable input is kept high. If an enable input is kept  
low for more than 2ms, the LED current for the respec-  
tive display is set to zero. If both enable inputs are kept  
low for more than 2ms, the MAX1575 enters shutdown.  
♦ 2.7V to 5.5V Supply Voltage Range  
♦ Soft-Start Limits Inrush Current  
♦ Output-Overvoltage Protection  
♦ Thermal-Shutdown Protection  
♦ 16-Pin Thin QFN 4mm x 4mm Package  
Ordering Information  
The MAX1575 is available in a 16-pin 4mm x 4mm thin  
QFN package (0.8mm max height).
