Product Brief  
CHARGE PUMP CURRENT SOURCE FOR LED DRIVER WITH BRIGHTNESS CONTROL  
AP3605  
Description  
Parametric Table  
The AP3605 is a step-up DC/DC converter based on 1.5x  
charge pump current source, it is specially designed for  
LED supplies in backlight display.  
Input Voltage (V)  
2.7 to 5.5  
1.5  
Supply Current (Typ) (mA)  
Operating Frequency (Typ) (MHz)  
Efficiency (Typ) (%)  
1.0  
The AP3605 can provide constant current up to 20mA for  
each LED, which is programmed by an external resistor,  
so it has a total capability to provide 80 mA for 4 LEDs.  
The chip has a good performance of LED current  
matching and allows PWM brightness dimming control.  
Additionally, high switching frequency up to 1 MHz  
enables the use of two small external flying capacitors.  
Internal soft-start circuitry prevents excessive inrush  
current during start-up.

The AP3605 supply voltage range is from 2.7V to 5.5 V,  
ideally suited for applications powered by the Li-ion  
battery.  
Package  
The AP3605 is available in a 3mm*3mm QFN-3x3-16  
tiny package. Its operating temperature range is -40oC to  
85oC
