ISL97632IRT18Z-TK is a PMIC (Power Management IC) with LED driver capability designed for the automotive industry. This device is designed for use in applications where the requirements for efficiency and reliability are critical. ISL97632IRT18Z-TK is a buck-boost converter with the ability to switch from buck to boost and vice versa, while providing two or more channels of output power. In addition, the device offers high efficiency and low EMI (Electromagnetic Interference).

The application field of the ISL97632IRT18Z-TK mainly involves automotive interior and exterior lighting. It is ideal for LED backlighting in automotive displays, instrument panels and infotainment systems, as well as for forward- and rear-lighting applications in vehicle headlights and taillights.

The working principle of the ISL97632IRT18Z-TK is quite simple. It is based on a buck-boost topology that allows it to switch from buck to boost operation depending on the voltage levels in the system. The device takes in an input voltage and then steps it up or down depending on the output voltage levels required. This is done by the use of two synchronous-rectifying MOSFETs, one acting as the high-side switch, and the other as the low-side switch.

As the device steps up or down a voltage, it also regulates the output current. This is done using a current-sensing circuit that reads the load current and adjusts the duty cycle of the two MOSFETs accordingly. This ensures that the output current remains constant and that the device operates without interference.

In addition, the ISL97632IRT18Z-TK offers several protection features, including a thermal shutdown circuit, an undervoltage lockout circuit, and an output overcurrent protection circuit. This ensures that the device operates safely and reliably, even under extreme environmental conditions.

The ISL97632IRT18Z-TK is a highly efficient PMIC (Power Management IC) with LED driver capability designed for the automotive industry. It is suitable for both buck and boost operation and features a current-sensing circuit for output current regulation. Additionally, the device offers a variety of protection features for safe and reliable operation in even the most extreme conditions.
