AL5809
60V Two Terminal Constant Current LED Driver
PowerDI
Description
The AL5809 is a constant current linear LED driver and it provides a
cost-effective two pin solution. It has an excellent temperature
stability of 20ppm/°C and the 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.
The AL5809 turns on when the voltage between IN and OUT swings
from 2.5V up to 60V enabling it 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.
The AL5809 is available in either thermally robust package
PowerDI123 or SOD-123 package.

AL5809
Application Information
Description
The AL5809 is a constant current Linear LED driver and can be placed in series with LEDs as a High Side or a Low Side constant current
regulator. The AL5809 offers various current settings from 15mA up to 150mA and different current settings available upon request (contact
Diodes local sales office at http://www.diodes.com).
The AL5809 contains a Low-Dropout regulator which provides power to the internal Current regulation control block. A fixed preset LED current
setting resistor sets the reference current of the Current regulation block. The LED current setting resistor varies with each variant of the AL5809.
An accurate current mirror within the Current regulation control block increases the reference current to the preset LED current of the AL5809.
Simple LED String
The AL5809 can be placed in series with LEDs as a Low Side/High Side constant current regulator. The number of the LEDs can vary from one
to as many as can be supported by the input supply voltage. The designer needs to calculate the maximum voltage between In and Out by
taking the maximum input voltage minus the voltage across the LED string (Figures 1 & 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 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 4a) applying a PWM
signal with a frequency range between 100Hz and 200Hz. The Out pin current is then effectively switched on and off to modulate the output LED
current. The dimming effect can be achieved by varying the PWM signal duty cycle.

Test conditions (Figure 4a): PWM frequency 100Hz200Hz Square wave, 0-4V gate voltage, VIN = 6V, 1 LED, AL5809-30mA
Use the following formula to calculate the Min and Max duty cycle:
Min. Duty cycle (%) = (tON_MIN) / (time period of the PWM signal)
Max. Duty cycle (%) = 100% - ((tOFF_MIN) / (time period of the PWM signal))
Notes: tON_MIN = 0.5mS (Min. value), and tOFF_MIN = 0.5mS (Min. value) are listed in the Electrical Characteristics table on page 4.

Application Information (cont.)
Power Dissipation
The maximum ambient temperature range of the AL5809 is determined by its power dissipation and thermal impedance of the PCB onto which it
is mounted. Its junction temperature must be kept equal to or less than +125°C.
The power dissipated is determined by the LED current version that has been selected (15, 20, 25 30, 40, 50, 60, 90, 100, 120 or 150mA) and
the difference between the input voltage and LED chain voltage.
VINOUT * ILED
In a typical 12V system, the input voltage can vary between 11.4V and 12.6V. The recommended minimum VINOUT voltage of 2.5V enables the
AL5809 to drive 2 LED in series from the 12V rail (assuming VLED <3.25V).
The AL5809’s power dissipation under minimum input voltage conditions will be: VINOUT * ILED = (11.4-6.5) * ILED
So for the 20mA AL5809-20PI under these conditions this equals: 4.9V * 20mA = 98mW
Under maximum input conditions (12.6V) the AL5809’s power dissipation will be: VINOUT * ILED = (12.6-6.5) * ILED
So for the 20mA AL5809-20QPI this equals: 6.1V * 20mA = 122mW
So there is a large difference in power dissipation of the Linear LED driver between minimum and maximum battery voltages. And care must be
taken to calculate expected power dissipations and then determine the suitable PCB material and layout. See Figures 9, 10 and 11 for graphs
showing power dissipation and maximum VINOUT, for different currents and PCB material. Maximizing the area and mass of the ground plane and
additional vias between the pad of the OUT pin will improve the thermal impedance (JA) of the AL5809.
