AL5809
60V Two Terminal Constant Current LED Driver
Description
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.
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.
The AL5809 is available in thermally robust package POWERDI-123
or SOD-123 package.

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.
