LT6656ACDC-5#TRMPBF: application and working principle

PMIC (power management integrated circuits) are special ICs specially designed for managing and controlling a variety of power functions inside the main IC. Voltage references are a type of PMIC which basically keep the tracked voltage within a specified range. Voltage references have their own application fields and their own working principles. LT6656ACDC-5#TRMPBF is an example of voltage reference PMIC which occupies an important place in the world of power management ICs. In this paper, we shall discuss the application and working principle of LT6656ACDC-5#TRMPBF.The LT6656ACDC-5#TRMPBF is a low-voltage reference GMIC that provides an output voltage with high accuracy over a wide temperature range. It is a fixed 5.000-V precision reference with an initial accuracy of 0.15%. This product ensures low drift with increasing temperature and its 185-ppm/°C temperature coefficient ensures that the output voltage can maintain constant accuracy over the specified temperature range.In terms of its operating temperature range, the LT6656ACDC-5#TRMPBF operates from –55°C to 125°C, making it suitable for applications that require a very wide range of ambient temperatures, such as industrial and consumer products. In terms of its output current, the output current of LT6656ACDC-5#TRMPBF can range from 1mA to 8mA, depending on the operation mode. The precise accuracy of the output voltage is ensured by its built-in precision trimming resistors. Furthermore, the IC is also equipped with protective features such as short-circuit, reverse-polarity, and reverse-current protection.In terms of its application, the LT6656ACDC-5#TRMPBF is used in many industries as a precise reference voltage source.
