概述
Description
The LT8631UX is a high-efficiency, synchronous step-down switching regulator from Analog Devices. It operates over a 3V to 42V input range and delivers up to 10A of output current with minimal external components.
Key features include:
- Ultra-low quiescent current (2.5µA in sleep mode), ideal for battery-powered applications.
- High efficiency (up to 97%) across a wide load range.
- Fast switching frequency (up to 3MHz), allowing for compact designs.
- Advanced control loop for excellent transient response.
- Integrated power switches and protection features (thermal shutdown, UVLO, and current limiting).
The LT8631UX is well-suited for automotive, industrial, and telecom applications requiring high performance in a small footprint. Its Silent Switcher® architecture minimizes EMI, making it ideal for noise-sensitive systems.
For detailed specs, refer to the datasheet on Analog Devices' website.
