Product Overview
The LTC3866EUF#PBF is a dual-phase synchronous buck DC/DC controller designed for high-current power systems requiring scalable performance and tight regulation. It integrates dual current mode control loops with output voltage tracking, precision soft-start, and PMBus communication for system monitoring and configuration. The device supports phase interleaving to reduce input ripple and improve transient response, making it ideal for server, telecom, industrial, and high-performance computing power rails.
