Analog Devices Inc. LTC7812EUH-PBF is a high-performance, dual-output, synchronous buck-boost DC-DC controller. This versatile device is designed for step-up and step-down power conversion, featuring a wide input voltage range of 4.5V to 38V. The controller operates with selectable switching frequencies between 115kHz and 835kHz, with a typical range of 350kHz to 535kHz, enabling optimized efficiency and component size. Key control features include enable, frequency control, power good reporting, soft start, and tracking capabilities. The LTC7812EUH-PBF is housed in a 32-QFN (5x5mm) exposed pad package, suitable for surface mounting. Its transistor driver output and positive output configuration make it applicable in automotive, industrial, and telecommunications power supply applications. The operating temperature range is -40°C to 125°C (TJ).
