The LT8705AEUHF#PBF from Analog Devices is a high-performance, 80V synchronous 4-switch buck-boost DC/DC controller. This controller is designed to operate efficiently with input voltages that can be above, below, or equal to the regulated output voltage.
Key electrical specifications include an input voltage range from 2.8V (with EXTV IN CC > 6.4V) up to 80V, and an output voltage range from 1.3V to 80V. It features synchronous rectification for high efficiency, achieving up to 98%. The device supports a synchronizable fixed switching frequency adjustable from 100kHz to 400kHz.
Integrated feedback loops for input current, input voltage, output current, and output voltage simplify design. The LT8705AEUHF#PBF is suitable for a wide array of applications including solar, automotive, and telecom power management systems. It is available in a 38-lead QFN package with a surface mount type.
This controller offers features like input and output current monitoring pins and improved light load transitions. The operating temperature range is -40°C to 125°C.
