* IOUT
– 10mA ±10% Constant Current (Preset)

Application

as long as the maximum supply voltage to the device is < 40V. With the low-side control, the BCR421UFD has an Enable (E.

Description

The BCR420UFD and BCR421UFD monolithically integrate transistors, diodes and resistors to function as a Constant Current Regulator (CCR) for linear LED driving. The device regulates with a preset 10mA nominal that can be adjusted with an external res.
