MP1523  
Precision 6-Lamp  
White LED Driver  
Monolithic Power Systems  
DESCRIPTION  
FEATURES  
The MP1523 is a 5-pin SOT23 step-up  
converter designed for driving up to six (6)  
series white LEDs from a single-cell Lithium  
Ion battery. The MP1523 uses a current limited,  
variable frequency architecture to regulate the  
LED current, which is measured through an  
external current sense resistor. Its low 0.4V  
feedback threshold reduces power loss and  
improves efficiency. To prevent damage due to  
an open circuit condition, the BIAS pin can  
measure the output voltage and turn off the  
converter if an over-voltage condition is  
present.  
On Board Power MOSFET  
Drives up to 6 White LEDs  
Up to 90% Efficiency  
Over 80mA Output Current Capacity  
Open Load Shutdown  
Low 0.4V Feedback Threshold  
UVLO, Thermal Shutdown  
Soft-Start  
Internal Current Limiter  
Available in SOT23-5 Package  
Evaluation Board Available  
APPLICATIONS  
The MP1523 includes under-voltage lockout,  
current limiting, and thermal overload  
protection to prevent damage in the event of  
an output overload. The MP1523 is available in  
a small 5-pin SOT23 package.
