Quality Control: Learn More
The Analog Devices Inc. LTC3779HFE-TRPBF is a high-performance buck-boost DC-DC controller designed for step-up and step-down voltage regulation. This component supports a wide input voltage range from 4.5V to 150V and features a single positive output configuration. The controller operates with a switching frequency adjustable from 50kHz to 600kHz, enabling efficient power conversion. Key control features include current limiting, power good indication, and soft-start functionality for smooth power-up sequences. The LTC3779HFE-TRPBF incorporates a synchronous rectifier for enhanced efficiency and is packaged in a 38-TSSOP-EP (38-TFSOP) surface-mount package, supplied on tape and reel. Its robust design makes it suitable for applications in industrial automation, automotive, and data center power supplies. The maximum duty cycle is 90%, and it operates across an ambient temperature range of -40°C to 150°C.
