AL5809
60V Two Terminal Constant Current LED Driver
Pin Assignments
The AL5809 is a constant current linear LED driver and provides a
cost-effective two pin solution. It has an excellent temperature
stability of 20 ppm/°C and current accuracy ±5% regulated over a
wide voltage and temperature range. The AL5809 comes in various
fixed output current versions removing the need for external current
setting resistors creating a simple solution for the linear driving of
LEDs. It supports both the high-side and low-side driving of LED
chains.
AL5809
The AL5809 turns on immediately and can swing from 2.5V up to
60V enabling drive long LED chains. The floating ground, 60V
voltage rating between input and output pins designed to withstand
the high peak voltage incurred in offline applications.

Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be
affected by exposure to absolute maximum rating conditions for extended periods of time.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when
handling and transporting these devices.

Application Information
Description
Simple LED String
The AL5809 can be placed in series with LEDs as a Low Side/High Side constant current regulator. The number of LEDs can vary from one to
as many as supported by the input supply voltage. The designer needs to calculate the maximum voltage between In and Out by taking the
maximum input voltage less the voltage across the LED string (Figures 1 and 2).

The AL5809 can also be used on the high side of the LEDs, see Figure 2. The minimum system input voltage can be calculated by:
VIN(min) = VLED_CHAIN + 2.5V
Where VLED_CHAIN is the LED chain voltage.
The LED current can be increased by connecting two or more AL5809 in parallel shown in Figure 3.

PWM Dimming
The AL5809 can be used to provide LED current dimming driving the Out pin via the MOSFET switch to ground (Figure 4). The Out pin current is
then effectively switched on and off causing the LED current to turn on and off.
