The Richtek RT8468GS is part of a family of LED drivers that emits a constant current output and is widely used in LED drivers. It has several features that make it an ideal choice for many applications.

The RT8468GS is designed for high power, high efficiency applications and can support up to 8 LEDs in series or parallel configurations. It has a wide supply voltage range and can support up to 85V without requiring external components. The RT8468GS also has a low quiescent current of less than 10mA, making it an ideal choice for point of load applications, including LED lighting and home appliance lighting.

The RT8468GS also features over-current and short-circuit protection which provides a level of protection for the LED drivers from unexpected current and voltage changes. It also has thermal protection to ensure that it does not overheat. It has a high efficiency, low heat dissipation, and a wide dimming range, making it an ideal choice for many LED lighting applications.

In addition, the RT8468GS also features over-voltage protection which prevents the voltage to exceed the limits of the LED. This feature also helps to protect the LED from unexpected current and voltage changes. The RT8468GS also has a wide dimmer input range, allowing it to work with many different dimmer systems.

The RT8468GS’s operating temperature range is from -40°C to 125°C, making it suitable for a wide range of applications. It is UL, CE, and ROHS compliant, making it suitable for commercial, industrial, and residential applications.

The RT8468GS comes in two primary configurations: buck and boost. The buck configuration can be used to provide a constant supply of current and faster response times. The boost configuration can be used to provide an adjustable output voltage and ensure that current is not exceeded.

The working principle of the RT8468GS is that it takes a DC input voltage and increases or decreases it depending on the configuration selected. It then uses the input voltage and current to calculate the output voltage and current. The output voltage is then regulated by an onboard PWM controller. The PWM controller then uses the input voltage and current to control the LED current. The LED current is then used to regulate the output voltage.

The RT8468GS is a great choice for LED driver applications. Its wide supply voltage range, low quiescent current, thermal protection, and over-voltage protection make it an ideal choice for many LED lighting applications. Its buck and boost configurations allow it to work with a wide variety of dimmer systems, making it an ideal choice for many different applications. Its UL, CE, and ROHS compliance further adds to its adaptability.
