The BCR421UFD-7 from Diodes Incorporated is a monolithic linear constant current regulator (CCR) designed for efficient LED driving. It integrates transistors, diodes, and resistors to regulate current, with a preset nominal output of 10mA that can be adjusted up to 350mA using an external resistor.
This device is suitable for applications requiring a supply voltage of up to 40V. The BCR421UFD-7 features low-side control with an Enable (EN) pin, allowing for pulse-width modulation (PWM) up to 25kHz for LED dimming. It also incorporates a negative temperature coefficient (NTC) that reduces output current with increasing temperature, providing self-protection.
Packaged in a compact 2x2x0.6mm U-DFN2020-6 package, the BCR421UFD-7 minimizes PCB area and off-board height, making it ideal for low-profile applications like edge lighting strips. Its integrated design reduces component count and simplifies assembly.
Applications include edge lighting strips, emergency lighting, signage, decorative lighting, and retail lighting in refrigerated displays. The device is RoHS 3 compliant and halogen-free.
