LT8620IUDD#PBF Application Field and Working Principle

The LT8620IUDD#PBF belongs to a family of DC/DC Switching Regulators, and more specifically, to PMIC (Power Management Integrated Circuit) voltage regulators. This component is a sub-category of a more vast family of integrated circuits designed specifically for managing, regulating and switching power in micro-electronic systems.

Field of Applications

The LT8620IUDD#PBF is an intermediate voltage voltage regulator which is designed to replace complex discrete designs in portable devices and other applications where space, cost and efficiency is a priority. It provides high efficiency in both parallel and single-channel operation, making it suitable for use in many applications, including automotive, specialty-vehicle, and unmanned aerial vehicle (UAV) systems. The component can also be used in battery- or AC-powered equipment such as mobile phones, notebook computers, Blu-ray players and medical monitoring equipment. Its high current rating and high switching frequency allow it to be used in many high-performance applications.

Working Principle

The working principle behind the LT8620IUDD#PBF DC/DC switching regulator is relatively simple. The component integrates an external inductor, two current-mode Pulse Width Modulation (PWM) controllers, two power MOSFET switches and two low side MOSFET devices. This set-up provides a single-channel and a parallel-channel configuration with the possibility of achieving a wide range of input and output voltages.

The LT8620IUDD#PBF also integrates several protection features, including input under-voltage lockout (UVLO), output over-current protection (OCP), and output over-voltage protection (OVP). Additionally, the integrated digital-to-analog converters (DACs) allow the user to adjust both the switching frequency and the output voltage levels to meet the needs of the system.

The component operates with a wide range of input voltage, making it suitable for either battery-powered or line-powered systems. It is able to remain in regulation even when subjected to input/output transients. Furthermore, the component is capable of operating at a high efficiency over a wide temperature range. This high efficiency, coupled with its low quiescent current and low noise, makes it a very attractive component for high-performance applications.
