DESCRIPTION  
FEATURES  
The MP1518 is a step-up converter designed for  
driving up to 6 series white LEDs from a single  
cell Lithium Ion battery. The MP1518 uses current  
mode, fixed frequency architecture to regulate the  
LED current, which is measured through an  
external current sense resistor. Its low 104mV  
feedback voltage reduces power loss and  
improves efficiency. The OV pin monitors the  
output voltage and turns off the converter if an  
over-voltage condition is present due to an open  
circuit condition.  
On Board Power MOSFET  
Drives up to 6 Series White LEDs  
Up to 87% Efficiency  
Over 1MHz Fixed Switching Frequency  
Open Load Shutdown  
Low 104mV Feedback Voltage  
Soft-Start/PWM Dimming  
UVLO, Thermal Shutdown  
Internal Current Limit  
Available in TSOT23-6 and QFN8 Packages  
APPLICATIONS  
The MP1518 includes under-voltage lockout,  
current limiting and thermal overload protection  
preventing damage in the event of an output  
overload.  
Cell Phones  
Handheld Computers and PDAs  
Digital Still Cameras  
Small LCD Displays  
The MP1518 is available in small 6-pin TSOT23  
or 8-pin QFN (2mm x 2mm) packages.  
“MPS” and “The Future of Analog IC Technology” are Trademarks of Monolithic  
Power Systems, Inc.  
Also available is the MP1518DJE, ideal for  
applications where low EMI is critical.
