ISL6260CCRZ-T is a special purpose voltage regulator belonging to the family of PMIC (Power Management Integrated Circuits) voltage regulators. It is specifically designed for offline AC/DC SMPS (Switched Mode Power Supplies) applications. The ISL6260CCRZ-T voltage regulator integrates the rectifier, PFC (Power Factor Correction) pre-regulator, digital controller and power MOSFETs in a single unit, which ensures an optimized size, ease for the designer, cost efficiency and performance of the entire supply system.

The working principle of the ISL6260CCRZ-T is based on the flyback topology. This topology is characterized by two devices that work together to form an oscillator. The first device is a PFC pre-regulator, and the other is the primary side switching power MOSFET. The PFC pre-regulator senses the current through the primary side power switch and supplies the necessary signal to it, allowing it to switch at the right instant. The signal is also fed back to the primary circuit, allowing the current to be limited. With this feedback loop in place, the voltage across the primary side power switch is limited, thus eliminating the risk of overvoltage. Meanwhile, the secondary side of the power supply is kept in regulation under all conditions.

In addition, the ISL6260CCRZ-T supports other features such as overvoltage and undervoltage protection, overcurrent protection, and soft-start. These features allow for a higher level of protection and enhance the performance of the entire system. Additionally, the ISL6260CCRZ-T also has integrated digital controllers and drivers to reduce the number of external components. These features allow for greater system efficiency, reduced overall system cost, and improved sophistication in the control system.

The ISL6260CCRZ-T is ideal for a wide variety of offline AC/DC SMPS applications, such as personal computers, industrial equipment, and consumer electronic devices. Its high-efficiency and power density, along with its reliable protection features, make the ISL6260CCRZ-T the ideal choice for these applications. With its integrated design and highly reliable performance, the ISL6260CCRZ-T provides an optimized solution for a wide variety of AC/DC SMPS applications.
