BCR402UW6Q-7 LED Drivers

BCR402UW6Q-7 are LED drivers that are widely used in Power Management Integrated Circuit (PMIC) applications. They offer a complete solution for driving LED strings in applications where efficiently managing power is important, such as portable devices, automotive electronics, LCD TVs and other dimmable appliances.The BCR402UW6Q-7 LED drivers are designed to provide excellent light-emitting efficiency, long lifetime, and very low power consumption, making them ideal for battery-powered applications. They feature a wide input voltage range and regulated multi-string output current, along with over current and thermal shutdown protection.

Application Field

BCR402UW6Q-7 LED drivers are suitable for applications in many fields, including smart lighting, instrumentation, displays, decoders, portable devices, automotive electric and other PMIC applications.In Smart lighting, the BCR402UW6Q-7 LED drivers are ideal for driving lighting in both indoor and outdoor applications, providing precise brightness control and precise color temperature control.In portable devices, the LED drivers are commonly used for backlighting displays, and for LED indicators. In automotive electric applications, the LED drivers are used to drive a variety of lighting components, such as interior lighting, exterior lighting, and indicators.

Working Principle

The working principle of the BCR402UW6Q-7 LED drivers is relatively simple. The drivers receive direct current (DC) electrical power from a power supply and regulate it to an output current that is suitable for use with LEDs.The BCR402UW6Q-7 LED drivers feature a current-singing configuration, which makes them more efficient than LED drivers with a voltage-regulator configuration. A current-sensing LED driver monitors the LED string voltages and adjusts the corresponding resistance to regulate the output current. This means that there is no need for costly external components, such as voltage regulators, to regulate the output current. The BCR402UW6Q-7 LED drivers also feature an adjustable current limit, which helps protect the LEDs from operating outside of their specified range, avoiding potentially hazardous thermal issues. Additionally, the LED drivers feature over-current and thermal protection limits, which are designed to protect the LED strings from potentially harmful electrical conditions. Finally, the BCR402UW6Q-7 LED drivers are designed to operate at a wide input voltage range, making them suitable for use in both AC and DC applications. The robust design also makes them suitable for use in adverse environments, such as automotive or industrial applications.

Conclusion

BCR402UW6Q-7 LED drivers are widely used in a variety of Power Management Integrated Circuit (PMIC) applications. They offer a complete solution for driving LED strings, providing excellent light-emitting efficiency, long lifetime, and very low power consumption. Additionally, the LED drivers feature adjustable current control and a wide input voltage range, making them suitable for use in both AC and DC applications.
