BCR421UW6 regulator equivalent, linear led constant current regulator.
* LED Constant Current Regulator using NPN Emitter-Follower with Emitter Resistor to Current Limit
* IOUT
– 10mA ± 10% Constant Current (Preset) <.
as long as the maximum supply voltage to the device is < 40V.
With low-side control, the BCR421U has an Enable (EN) pin.
The BCR420UW6 and BCR421UW6 monolithically integrate transistors, diodes, and resistors to function as a Constant Current Regulator (CCR) for linear LED driving. Each device regulates with a preset 10mA nominal that can be adjusted with an external r.
