Analog Devices Inc. LT3641IFE is a dual, high-voltage, monolithic buck switching regulator. This component features two independent step-down converters capable of delivering 1.3A and 1.1A respectively. The outputs are adjustable, with a minimum fixed output of 0.6V and 1.265V, and an adjustable maximum output up to 39.48V. The switching frequency is configurable from 500kHz to 2MHz, allowing for optimization of component size and efficiency.
The LT3641IFE operates from an input voltage range of 2.5V to 42V, making it suitable for a broad spectrum of power supply applications. Its topology is buck, and both outputs incorporate synchronous rectification for improved efficiency. The device is housed in a 28-TSSOP-EP package with an exposed pad for enhanced thermal performance, suitable for surface mounting. This high-performance regulator finds application in automotive, industrial, and battery-powered systems demanding robust and efficient power conversion.
