BCR420UW6
Description
The BCR420UW6 and BCR421UW6 monolithically integrate transistors, diodes, and resistors to function as a Constant Current Regulator (CCR) for linear LED driving. Each device regulates with a preset 10mA nominal that can be adjusted with an external resistor up to 350mA.
Key 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
- Low-Side Control Enabling PWM Input < 25kHz (BCR421U)
- Negative Temperature Coefficient (NTC) Reduces IOUT with Increasing Temperature
- Parallel Devices to Increase Regulated Current
- Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
- Halogen and Antimony Free. “Green” Device (Note 3)
