AP8800A  
COST EFFECTIVE 28V BUCK 1-W LED DRIVER  
Description  
Pin Assignments  
The AP8800A is a step-down DC/DC converter designed to  
drive LEDs with a constant current. The device can drive up  
to 7 LEDs, depending on the forward voltage of the LEDs, in  
series from a voltage source of 8V to 28V. Series connection  
of the LEDs provides identical LED currents resulting in  
uniform brightness and eliminating the need for ballast  
resistors. The AP8800A switches at frequency up to 600kHz.  
This allows the use of small size external components, hence  
minimizing the PCB area needed.

Maximum output current of AP8800A is set via an external  
resistor connected between the VIN and SET input pins.  
Dimming is achieved by applying either a DC voltage or a  
PWM signal at the CTRL input pin. An input voltage of 0.2V  
or lower at CTRL switches off the output MOSFET simplifying  
PWM dimming.
