BCR420UFD / BCR421UFD  
LINEAR LED CONSTANT CURRENT REGULATOR IN U-DFN2020-6  
Description  
Features  
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 preset  
10mA nominal that can be adjusted with an external resistor up to  
350mA. It is designed for driving LEDs in strings and will reduce  
current 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.  
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 1.7W in U-DFN2020-6 Package  
0.6mm Height for Low-profile Edge Lighting  
Low-Side Control Enabling PWM Input < 25kHz (BCR421U)  
Negative Temperature Coefficient (NTC) Reduces IOUT with  
Increasing Temperature  
With the low-side control, the BCR421U has an Enable (EN) pin  
which can be pulse-width modulated (PWM) up to 25kHz by a micro-  
controller for LED dimming.  
Parallel Devices to Increase Regulated Current  
Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)  
Halogen and Antimony Free. “Green” Device (Note 3)  
Automotive-Compliant Parts are Available Under Separate  
Datasheet (BCR420UFDQ/BCR421UFDQ)  
With no need for additional external components, this CCR is fully  
integrated into a 2x2x0.6mm package (U-DFN2020-6) minimizing  
PCB area, off-board height, and component count.
