Description
The BCR420UFD and BCR421UFD 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.
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 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 Temp.
