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-DFN20

Applications

* as long as the maximum supply voltage to the device is < 40V. With the low-side control, the BCR421UFD has an Enable (EN) pin which can be pulse-width modulated (PWM) up to 25kHz by a microcontroller for LED dimming. With no need for additional external components, this CCR is fully integrated into
