Constant-current LED drivers

30 January 2019 Opto-Electronics Power Electronics / Power Management

Infineon Technologies’ LITIX Basic+ LED drivers serve as an extension to the existing LITIX Basic family.

The new linear constant current sources, with their 1 to 3 inputs/outputs, build a scalable family to reduce system costs through the need for fewer external components and the introduction of a power shift feature.

Output currents from 5 mA up to 360 mA (with power shift) can be served with this driver family, which also has optimised diagnosis features as well as improved output current accuracy. Several selectable fault management modes offer high design-in flexibility.

The devices’ flexible Single LED Short (SLS) feature puts them into either a latched off-state, active retry or simply diagnosis without channel deactivation. Design flexibility is provided through footprint compatibility across the entire family.
