Introduction to MAX20098ATEA/VY+

MAX20098ATEA/VY+ is a PMIC (power management IC) in the LED driver family. It is a type of integrated circuit designed to efficiently convert electrical power from a high input voltage to a low output voltage. The MAX20098ATEA/VY+ is a solution for powering and managing high-brightness LEDs at large currents in a wide range of applications. It comes in an ultra-compact 2 mm x 2 mm package and provides a wide input voltage range from 3.2 to 24V. It also features a high-accuracy current-source control mode that allows the output current to be programmed between 25 and 1000mA.

Application Field of MAX20098ATEA/VY+

MAX20098ATEA/VY+ is well suited for various applications due to its wide input voltage range and high current capability. It is used in automotive lighting, decorative lighting, backlighting, and more. The MAX20098ATEA/VY+ is also used in video displays and projectors, portable devices such as mobile phones, handheld power supplies, and power adapters. It is an ideal choice for applications where an efficient, compact, and cost effective solution is needed.

Working Principle of MAX20098ATEA/VY+

The MAX20098ATEA/VY+ uses a combination of two independent power conversion circuits to achieve a high-efficiency LED driver solution. The first circuit is a boost converter that outputs a low-ripple and adjustable output voltage from 3.2V up to 24V. The second circuit is a high-accuracy current-source controller that ensures a stable LED current at any input voltage or load. The boost converter circuit is developed to regulate the output voltage in a range from 3.2V up to 24V. It is powered from the input voltage and provides constant current to the LED string. The output voltage of the boost converter is then fed to the high-accuracy current source controller circuit, which regulates the LED current according to the programmed value. The MAX20098ATEA/VY+ uses a proprietary control loop based on a Constant Current-Frequency Control (CCFC) algorithm to ensure a precise constant-current output.

Conclusion

As a conclusion, with its wide input voltage range and impressive current-source capability, the MAX20098ATEA/VY+ is a great choice for various lighting applications. Its CCFC control loop ensures a stable output current over the entire input voltage and load range, which makes it an ideal solution for efficient, cost-effective, and compact LED driver systems.
