The RT8471GFP is a new variable low-voltage high-current Low-Side Switch IC from Richtek Technology Corporation. The device is composed of a PMIC(Power Management Integrated Circuit) and LED Drivers, providing an optimized solution for power management, LED illumination and battery driving applications. On the backside, it also improves the total operating efficiency by integrating a low quiescent current startup circuit, which minimizes live power consumption.The integrated Power MOSFETs in the RT8471GFP can handle up to 4A of load current, making it ideal for driving light-emitting diodes (LEDs). The device also features adjustable over-Temperatures protection and over-current protection, designed to protect the output over overload or short circuit. Additionally, the RT8471GFP can be configured with both analog and digital input/output levels,but like any other PMIC, it works also in a color temperature cotrollable mode, allowing for dimming.The RT8471GFP also provides numerous LED driver functions, such as flicker-free Dim2 and 3 step dimming. This allows for smooth, flicker-free dimming with PWM signals, ideally suited for consumer electronics like HD TVs, LCDs and monitors. The integrated DC/DC converter features 1.5MHz switching, while offering a high efficiency of up to 90%.Additionally, the RT8471GFP is capable of supplying voltage levels between 1V to 150V and providing up to 4A of current, allowing the output to easily achieve the desired luminosity. This can be done by controlling the brightness of the LEDs without the need for external components. Moreover, the RT8471GFP is equipped with a highly configurable voltage detector that can detect voltage levels up to 150V and provide accurate output even in the darkest of environment.Finally, the RT8471GFP also has a wide range of applications, from cell phones and televisions to industrial and automotive applications. It is a great solution for those demanding applications where power efficiency and brightness are essential.In conclusion, the RT8471GFP is a versatile and efficient PMIC with LED Drivers. It can deliver currents up to 4A, while providing adjustable over-temperature and over-current protection. Moreover, the integrated DC/DC converter provides an efficiency of up to 90% with a switching frequency of 1.5MHz. The device is well suited for a wide range of applications, from consumer electronics to industrial and automotive. The RT8471GFP helps bring light to a world in need of efficient and reliable power sources.
