Product Description

BCR420UW6-7 LED Lighting Drivers AD8626ARMZ-REEL PCA9450CHNY Linear Semiconductors




The BCR420U and BCR421U monolithically integrate transistors,diodes and resistors to function as a Constant Current Regulator(CCR) for linear LED driving. The device regulates with a preset10mA nominal that can be adjusted with an external resistor up to350mA. It is designed for driving LEDs in strings and will reducecurrent at increasing temperatures to self-protect. Operating as a
series linear CCR for LED string current control, it can be used in multiple applications, as long as the maximum supply voltage to the device is < 40V.

With the 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 an SOT26 (SC74R) minimizing PCB area and
component count.
