Data Sheet  
WHITE LED STEP-UP CONVERTER  
AP3019A  
Features  
General Description  
Inherently Uniform LED Current  
High Efficiency up to 84%  
No Need for External Schottky Diode  
Output Over-voltage Protection (OVP)  
Fixed 1.2MHz Switching Frequency  
Uses Tiny 1mm Tall Inductor  
The AP3019A is an inductor-based DC/DC converter  
designed to drive up to eight white LEDs in series for  
backlight. Only one feedback resistor is needed to  
control the LED current and obtain required  
brightness.  
Requires Only 0.22µF Output Capacitor  
A constant frequency 1.2MHz PWM control scheme  
is employed in this IC, which means tiny external  
components can be used. Specifically, 1mm tall  
inductor and 0.22µF output capacitor for a typical  
application is sufficient. Additionally, the Schottky  
diode in boost circuit is integrated on this chip.  
AP3019A also provides a disable pin to ease its use  
for different systems.  
Applications  
Cellular Phones  
Digital Cameras  
LCD modules  
GPS Receivers  
PDAs, Handheld Computers  
The output over-voltage protection is implemented in  
AP3019A. When any LED is broken or in other  
abnormal conditions, the output voltage will be  
clamped.  
The AP3019A is available in standard SOT-23-6 and  
TSOT-23-6 packages.
