60V, LINEAR 75mA ADJUSTABLE CURRENT LED DRIVER

Description

Pin Assignments

The AL5811 is a Linear LED driver with an adjustable LED current up

to 75mA offering excellent temperature stability and output handling

capability. The AL5811 simplifies the design of linear and isolated or

non-isolated LED drivers by setting the LED current with standard

value resistors.

The AL5811 has an open drain output that can swing from 1V up to

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

outside of the LED current path and so accuracy is maintained while

minimizing the required overhead 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 75mA.

Longer LED chains can be driven by tapping V_CCfrom the chain,

where the chain voltage may exceed 60V.
