AL5812 Adjustable Linear LED Driver

Diodes Incorporated AL5812 Adjustable Linear LED Driver drives LED chains up to 59V with a constant current up to 150mA. The AL5812's 60V capability enables it to drive long LED chains (up to 16 white LEDs) while operating from rails as low 3.5V. This allows the device to operate with 5V, 12VAC/DC, 24VAC/DC, and 48VDC rails. The AL5812 operates with a minimal amount of external components - just a decoupling capacitor and a high value LED current setting resistor - which allows the use of small size and cost external components and results in a small solution footprint. The accuracy, temperature range, and cost make it ideally suited to cost-sensitive lighting applications.
