ISL80020AFRZ-T application field and working principle

The ISL80020AFRZ-T is a high power synchronous buck voltage regulator belonging to the DC-DC Switching Regulators series within the PMIC - Voltage Regulators product family. This buck converter offers a wide range of configurable input voltage, output voltage, and current requirements for multiple application scenarios. The ISL80020AFRZ-T synchronous buck regulator is designed specifically for a wide range of continuous current buck regulator applications. It has the capability to provide up to 10A of continuous current output. The device utilizes a high power bipolar NPN transistor to minimize losses and can operate from 3V to 24V input voltages. It also features programmable current limit and thermal protection abilities. The ISL80020AFRZ-T, being part of the DC-DC Switching Regulators PMIC product family, works through the buck converter principle. In a buck converter, an inductor is charged with an input voltage and when voltage is switched off, the inductor delivers power to the load. This way, the input voltage is transformed with a specified switching frequency into a desired output voltage.The ISL80020AFRZ-T also provides dynamic voltage scaling, adjustable PGOOD delay, and programmable soft-start duration, among other features. It offers precise voltage control with a typical line accuracy of ±0.6%, load regulation of± 0.3%, and peak current limit up to 20A. The device is therefore suitable for various systems with high power requirements and the need for precise voltage control, such as server, workstation and medical applications.The ISL80020AFRZ-T can operate from a wide input voltage range, from 4.5V to 24V, and can be used for multiple battery-powered applications. The device also features an integrated FET for high efficiency and provides an output voltage range from 0.6V to 12V. Moreover, it has an adjustable switching frequency from 150kHz to 800kHz, allowing for better noise control.Furthermore, the ISL80020AFRZ-T offers simple and reliable startup operation, as well as a current foldback capability to limit output current in applications with short circuit. This allows for the device to run at less than its max output current, thus preventing the system to overheat. The device also features adjustable frequency synchronous rectification, which improves efficiency and reduces power dissipation. In addition, the ISL80020AFRZ-T is equipped with a thermal protection circuit that limits power dissipation in the system. The device also provides a digital soft start feature, which allows it to gradually apply an output voltage, thus avoiding inrush current. Overall, the ISL80020FRZ-T is an ideal solution for powering the needs of a wide range of applications requiring high power buck regulator solutions. It offers various features for increased efficiency, reliability, and performance for the end user. The device\'s versatile design allows it to be used in a wide range of applications, including servers, workstations, medical, and battery-powered applications.
