ISL97900CRZ-T is an LED driver crafted by Intersil, which provides the ideal driving conditions for LED lighting, improving efficiency and lifespan when used correctly. It is royalty-free, making it a cost-effective solution to LED lighting applications, and is offered in a small, highly efficient 4 x 4 mm package.

The ISL97900CRZ-T is part of the ISL97900 series, which is part of the PMIC - LED drivers family. This family provides solution to maximize control of DC/DC converters and buck, boost, and buck-boost LEDs. The switch-mode regulators in the ISL97900 series, which include the ISL97900CRZ-T provide high-frequency, high-current and high-voltage driver solutions that define the next generation of high-efficiency, dimmable lighting solutions.

This driver offers the maximum level of efficiency, flexibility and performance in a compact, highly efficient 4 x 4 mm package. The ISL97900CRZ-T has an adjustable output current range from 100mA to 2000mA, allowing it to be used in a wide range of LED applications. It also offers enhanced EMI suppression with dual-mode PWM/ analog dimming, as well as a high-ripple-rejection ratio that ensures the quality of the light.

The key specifications of the ISL97900CRZ-T include an adjustable output current range of 100mA to 2000mA, a full-scale output current range of 16V, and an operating frequency of 1.3MHz. The driver is capable of providing a peak efficiency of up to 90% (with input voltage of 12V and output current of 1A). Additionally, the ISL97900CRZ-T features adjustable hold-up time, which can be changed from 6 to 20 milliseconds, allowing the user to optimize the LED luminescence for their applications.

The ISL97900CRZ-T LED driver works by taking an input voltage and regulating the output current to a value that the LED can be safely driven at, preventing excessive current draw, which reduces power consumption and extends LED life. This is achieved by the driver being capable of operating in either a switching or linear mode, with the switching mode providing improved power efficiency and the linear mode providing low acoustic noise. As current is regulated, the driver can be used to boost or buck the voltage, providing dimming control without needing complex dimmable controllers.

The ISL97900CRZ-T LED driver is the perfect solution for LED lighting applications, offering high efficiency and flexibility in a small package. It is highly efficient, with a peak efficiency of up to 90%, and it also offers adjustable output current, full-scale output current, adjustable hold-up time, and dual-mode PWM/analog dimming, making it an ideal solution for controlling LED lighting.
