ISL97692IIZ-T is an LED Driver chip that is classified as a PMIC (Power Management Integrated Circuit). The chip is used in a variety of applications, from TV sets and video monitors to LED displays and control panel systems.

The ISL97692IIZ-T LED Driver chip is the latest product from Intersil, which combines several features that make it a great candidate for LED applications. It has an input voltage range of 4.5V – 30V and provides up to 3.2A of output current at 40W.

The device is also capable of low frequency (up to 10kHz) dimming (pulse width modulation) and allows for constant current regulation of single and multiple LED strings. It is designed to provide fast, efficient and reliable performance, with minimal heat dissipation.

The working principle behind the ISL97692IIZ-T LED Driver chip is based on the use of a buck converter. The buck converter is used to convert an input voltage into a lower voltage which is then used to power the LEDs.

The device includes a low-side MOSFET switch and an oscillator. The oscillator generates pulses which activate the MOSFET switch. When the switch is turned on, the input voltage is then converted to a lower voltage for powering the LEDs.

The device also includes a smart current limiting circuit which helps it operate more efficiently. The circuit monitors the output current and is able to increase or decrease the duty cycle of the controller to ensure the LED current remains constant.

The device also includes programmable open and short LED string detection and compensation, as well as over temperature and over voltage protection. It is also equipped with soft start and fault protection features, making it a reliable and stable LED driver that can be used in a variety of applications.

Overall, the ISL97692IIZ-T LED Driver chip is a great choice for powering LEDs in applications such as TVs, video monitors, LED displays and control panel systems. With its combination of features and reliable performance, this chip is sure to provide your application with the best combination of efficiency and reliability.
