BCR40x linear regulators are tailored to drive low power LEDs with constant
current. BCR405U is suitable for LED applications with a wide range of supply
voltages from 1.4 V to 40 V. A multifunctional PWM input signal allows dimming
of the LEDs with an external PWM signal.
This example drives two ~11V Lumileds LEDs at around 60mA with
36V DC input, using a BCR405U.
