LTC3421EUF Description

Short technical summary and product information.

The LTC3421EUF is a switching voltage regulator manufactured by LT, now part of Analog Devices. This component is designed for step-down (buck) applications, providing an adjustable output voltage ranging from 2.4V to 5.25V with a maximum output current of 3A. It operates with an input voltage range of 0.5V to 4.5V and features a high switching frequency of 3MHz, which helps in reducing the size of external components.

 

The device is housed in a QFN-24 package and supports surface mount (SMD/SMT) technology, making it suitable for automated assembly processes. The minimum operating temperature is -40°C, and the maximum is 85°C, ensuring reliable performance across a wide temperature range. Its low operating supply current of 12 µA makes it an efficient choice for power-sensitive applications.

 

This regulator is part of the LTC3421 series and is classified under PMIC - Power Management ICs. The QFN-24 package is compact, and the surface mount design facilitates integration into various electronic circuits. The adjustable output type offers flexibility for designers needing specific voltage levels within the specified range.
