Overview

Infineon's linear LED driver ICs are the best choice for driving LED strings supplied by a DC voltage source in typical commercial lighting applications such as signage and LED strips but also automotive interior lights, emergency and multi-channel applications. The BCR linear drivers allow compact PCB designs, drive currents from 10 mA to 250 mA and they can be combined with an external power stage for higher power LEDs.

Key Features

  • Current from 10 mA to 250 mA
  • Requires a few small components
  • Space-constrained designs
  • Homogeneous light output with DC
  • Extra-low voltage drop (BCR431U)
  • Design flexibility at high power
  • PWM dimming at high frequencies
  • Flicker-free light

About

Extra-low voltage drop

The new-gen BCR430U and BCR431U feature an extra-low voltage drop which is ideal in cases where the supply voltage and forward voltage are very close together and voltage headroom is required. 

Cost- and space-efficient

Using linear constant-current LED driver ICs enables more design flexibility in applications with more LEDs on one strip and longer LED strips. Fewer feeding points are needed and costs can be saved in the overall system.

Saving space and components

Infineon’s linear constant current LED drivers only require few very small components and so are suitable for compact PCB designs with limited space. The BCR regulators drive currents from 10mA to 250mA, making them the ideal solution for low- and mid-power LEDs. For high-power LEDs, the linear constant-current LED controller IC in combination with an external power stage allows for high design flexibility.
