L5812

60V, 150mA ADJUSTABLE LINEAR LED DRIVER

Description

The AL5812 is an adjustable Linear LED driver offering excellent

temperature stability and output handling capability. The AL5812

simplifies the design of linear and isolated or non-isolated LED drivers

by setting the LED current with standard value resistors.

The AL5812 has an open drain output that can swing from 1V up to

60V enabling it drive long LED chains. Its low 0.5V R

SET

pin is outside

of the LED current path and so accuracy is maintained while

minimizing the required overheads to regulate the LED current. This

reduces its power dissipation when compared to traditional linear LED

drivers. This makes it ideal for driving LEDs up to 150mA (commonly

referred to as ½W LEDs).

Longer LED chains can be driven by tapping V

from the chain,

where the chain voltage may exceed 60V.

The AL5812 is available in the exposed pad MSOP-8EP and

U-DFN3030-6 packages.
