Product Description

The LT8708 Buck-Boost IC is a high-performance 80V DC-DC converter designed for seamless voltage regulation in wide-input applications. This QFN-28 Controller supports input voltages from 4V to 80V, enabling buck, boost, or buck-boost operation with adjustable output voltages. It integrates synchronous rectification for up to 98% efficiency and drives external MOSFETs for scalable current output. Suitable for automotive, industrial, and telecom systems, it operates across -40°C to 125°C. Key advantages include robust thermal performance, minimal external components, and reverse-voltage protection, though design complexity increases for high-power configurations. The device lacks built-in communication interfaces and direct battery management, requiring external circuitry for specific energy storage or monitoring needs. Screen and proximity sensing are not integrated.
