Description:
LTC3780 80W DC Buck Boost Converter Module is an adjustable DC-DC power supply module designed for applications where the input voltage may be either higher or lower than the required output voltage. Based on the LTC3780 buck-boost conversion architecture, the module can perform both step-down and step-up voltage conversion, providing greater flexibility than a conventional buck or boost converter.
It accepts a wide 5V to 32V DC input range and provides an adjustable output of approximately 1V to 30V DC, making it suitable for battery-powered equipment, electronics projects, laboratory applications, embedded systems, robotics and custom power supplies.
With an advertised power capability of up to 80W, this module is a versatile choice for projects requiring adjustable and regulated DC voltage from varying input sources.
