PMIC - LED Drivers

RT8510GQW is an integrated high-performance power management and LED driver IC, it can be applied to various power system architectures such as AC/DC power adapters, notebooks, interface bridges, and system monitors. As a LED driver IC, the RT8510GQW uses a high-precision brightness control algorithm to process the brightness level of a wide range of LEDs, providing full continuous lighting adjustment in the range of 0%-100%.

Application Field

The RT8510GQW provides an integrated solution for power management and LED driver applications, and incorporates many advanced features to ensure an optimal power supply design, such as input overvoltage protection, overcurrent protection, and power-on reset. It is designed for supporting wide current range applications, with a maximum combined maximum output current in continuous mode up to 600mA.

The RT8510GQW is mainly used for industrial and commercial LED lighting applications, particularly for interior lighting, automotive interior lighting and white goods panel-backlighting applications. It can also be used for backlighting displays, LCD and OLED panel lighting, LCD driver, and automotive head and tail lamps.

Working Principle

The RT8510GQW implements a variety of power regulation and protection functions. It uses a high-efficiency switch mode voltage regulation technique to output a precise voltage according to the supply voltage. The maximum voltage output is adjustable using an external resistive divider. The RT8510GQW also has a wide input voltage range, thus providing maximum flexibility to power sources.

Additionally, the RT8510GQW contains a Constant Current Limiting Loop (CCL) to provide current limiting protection. The CCL will turn off the driver output when the current exceeds pre-set maximum current threshold. This protection mode will avoid the high current induced stress on the output to assure the system reliability.

RT8510GQW has also built-in overvoltage protection. The protection circuit monitors the voltage level of the output and enables an overvoltage detector to detect the fault condition. When an overvoltage is detected, the protection circuit shuts down the driver output immediately.

Summary

The RT8510GQW is an integrated high-performance power management and LED driver IC, and is mainly used for industrial and commercial LED lighting applications. Its embedded high-precision brightness control algorithm allow continuous lighting adjustment in the range of 0%-100%. It also provides several protections, such as input overvoltage protection, overcurrent protection, and power-on reset. All in all, the RT8510GQW is an ideal choice for powering and controlling LED lighting systems.
