BCR421UW6, BCR420UW6 LINEAR LED CONSTANT CURRENT REGULATOR

BCR421UW6 Description

BCR420UW6 / BCR421UW6 LINEAR LED CONSTANT CURRENT REGULATOR IN SOT26 .
The BCR420UW6 and BCR421UW6 monolithically integrate transistors, diodes, and resistors to function as a Constant Current Regulator (CCR) for linear L.

BCR421UW6 Features

* LED Constant Current Regulator using NPN Emitter-Follower with Emitter Resistor to Current Limit
* IOUT
* 10mA ± 10% Constant Current (Preset)
* IOUT up to 350mA Adjustable with an External Resistor (BCR421U)
* VOUT
* 40V Supply Voltage
* PD up to 1W in SOT26

BCR421UW6 Applications

* as long as the maximum supply voltage to the device is < 40V. With low-side control, the BCR421U has an Enable (EN) pin which can be pulse-width modulated (PWM) up to 25kHz by a microcontroller for LED dimming. With no need for additional external components, this CCR is fully integrated into the S
