BCR402UW6

20 to 100mA LED CONSTANT CURRENT REGULATOR in SOT26

Description

Features

The BCR402UW6 monolithically integrates a transistor, diodes, and

resistors to function as a Constant Current Regulator (CCR) for LED

driving. The device regulates with a preset 20mA nominal that can be

adjusted with an external resistor up to 100mA. It is designed for

driving LEDs in strings and reduces current at increasing

temperatures to self-protect. Operating as a series linear CCR for

LED string current control, it can be used in applications with supply

voltages up to 40V.



LED Constant Current Regulator Using PNP Emitter-Follower

with Emitter Resistor to Current Limit



I_OUT= 20mA ± 10% Constant Current (Preset)

I_OUTup to 100mA Adjustable with an External Resistor

V_S– 40V Supply Voltage

P_Dup to 1W in SOT26

LED Dimming Using PWM up to 25kHz

Negative Temperature Coefficient (NTC) Reduces I_OUTwith

Increasing Temperature

Without requiring additional external components, this CCR is fully

integrated into the SOT26 package, minimizing PCB area and

component count.
