AL5811 Linear LED Driver

Diodes introduces the AL5811 family of simple 60 V, 75 mA Linear LED Drivers

Diodes' AL5811 Linear LED DriverThe AL5811 expands Diodes' Linear LED Driver family with a driver optimized to drive lower power LEDs. Like the AL5812, the device's 60 V capability enables it to drive long LED chains (up to 16 white LEDs) while operating from rails as low as 3.5 V. This allows the device to operate with 5 V, 12 V, or 24 V AC/DC, and 48 V DC rails.

The AL5811 operates with the minimal amounts of external components; just a decoupling capacitor and a high value LED current setting resistor. This allows the use of small size and low cost external components, resulting in a small solution footprint.

The accuracy, temperature range, and cost make it ideally suited to cost-sensitive lighting applications.

The AL5811 is available in MSOP-8EP and U-DFN3030-6 thermally enhanced packages which support linear operations over the wide operating voltage range and ambient temperatures.
