Description
The BCR420UW6 and BCR421UW6 monolithically integrate transistors, diodes, and resistors to function as a Constant Current Regulator (CCR) for linear LED driving.
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.
