BCR 420U E6433
Overview
Linear LED driver IC for low/medium power LEDs
The BCR420U linear LED driver IC is tailored to drive low and mid power LEDs in general and automotive lighting applications.
Summary of Features
- LED drive current preset to 10mA
- Output current adjustable by resistor up to 150mA
- Supply voltage up to 40V
- Low side current control, NPN transistor power stage
- PWM dimmable by external transistor
- Up to 1000mW power dissipation in a small SC74 package
- Negative thermal coefficient reduces output current at higher temperatures
- Automotive qualified according to AEC Q101
Benefits
- Driving current always under control for homogenous light output
- Longer lifetime of the LEDs due to reduced output current at higher temperatures (negative thermal coefficient)
- Easy paralleling of drivers to increase current
- Contributes to longevity and reliability of LED system
Potential Applications
- LED strips, signage and channel letters
- Commercial, architectural and residential lighting
- Shop, ship, train and aircraft lighting
- Automotive interior lighting
