AP5724  
WHITE LED STEP-UP CONVERTER  
General Description  
Features  
The AP5724 is a step-up DC/DC converter specifically designed  
to drive white LEDs with a constant current. The device can drive  
2~6 LEDs in series from a Li-Ion cell. Series connection of the  
LEDs provides identical LED currents resulting in uniform  
brightness and eliminates the need for ballast resistors. The  
AP5724 switches at 1.2MHz that allows the use of tiny external  
components. A low 0.1V feedback voltage minimizes power loss  
in the current setting resistor for better efficiency.  
Inherently Matched LED Current  
High Efficiency: 84% Typical  
Fast 1.2MHz Switching Frequency  
Current limit and UVLO Protections  
Internal Thermal Shutdown  
Internal Over Voltage Protection  
Integrated Soft-start Function  
SOT26 and DFN2020C-6: Available in “Green”
