The BCR series CCRs are designed to provide a constant output current over a wide range of input voltages. They are ideal for driving low-power LEDs and other devices that require a constant current source. With their low dropout voltage and built-in over-temperature protection, the BCR series provides a reliable and efficient solution for a wide range of applications. The different package options allow for flexibility in PCB design and layout.
Features
The main features of BCR series Constant Current Regulators may be summarized as follows:
1. Output currents ranging from 5 mA to 100 mA
2. Wide input voltage range (up to 450 V)
3. Low dropout voltage (0.5 V typical)
4. Built-in over-temperature protection
5. Low EMI/RFI noise
6. SOT-223, SOT-89, and TO-252 packages available
Applications
LED lighting (indicator lights, backlighting, automotive lighting, etc.)
Current sources for battery charging circuits
Low-power motor drive circuits
Voltage regulators for low-voltage applications
Portable devices (such as handheld meters and instruments)
As the current in LEDs must be carefully controlled, BCRs are commonly used to regulate the current and provide stable illumination.BCRs can also be used to control the current to the backlighting of LCD screens, ensuring that the screen displays at the correct brightness level. The BCRs can be used to drive the LEDs used in automotive lighting systems such as headlights, taillights, and turn signals.
