AL8807A  
HIGH EFFICIENCY LOW EMI WIDE ANALOG  
DIMMING RANGE 36V 1A/1.3A BUCK LED DRIVER  
Description  
Pin Assignments  
(Top View)  
The AL8807A is a step-down DC/DC converter designed to drive  
LEDs with a constant current. The device can drive up to 9 white high  
brightness LEDs in series from a voltage source of 6V to 36V.  
SW 1  
5 VIN  
The AL8807A has an extended CTRL pin voltage range; increasing  
its analog dimming range to greater than 10:1. The improved analog  
dimming range makes it suitable for a variety of lighting applications  
requiring wide analog dimming ranges.  
GND 2  
CTRL 3  
4 SET  
The AL8807A switches at frequency up to 1MHz with controlled rise  
and fall times to reduce EMI. This allows the use of small size  
external components, hence minimizing the PCB area needed.  
SOT25  
(Top View)  
Maximum output current of AL8807A is set via an external resistor  
connected between the VIN and SET input pins.  
SET 1  
GND 2  
GND 3  
CTRL 4  
8 VIN  
7 N/C  
6 SW  
5 SW  
Over Temperature Protection is incorporated so that should a fault  
occur the device will automatically shut-down and only restart when  
its junction temperature has cooled down,
