SIC450ED-T1-GE3

The Vishay Dale SIC450ED-T1-GE3 is a PMBus 1.3 compliant, non-isolated DC/DC buck regulator designed for high-current applications. It features integrated MOSFETs and can deliver up to 40 A of continuous output current from a 4.5 V to 20 V input voltage range.

This regulator offers a digitally adjustable output voltage from 0.3 V to 12 V with switching frequencies up to 1.5 MHz. Its architecture provides ultrafast transient response and tight regulation over a broad load range. The device includes integrated internal compensation, making it stable with various output capacitor types. A power-saving scheme is incorporated to enhance light-load efficiency.

The SiC450ED-T1-GE3 is available in a lead-free, power-enhanced MLP 5 mm x 7 mm package, suitable for surface mount applications. It supports various PMBus commands for configuration and monitoring, including voltage, current, and temperature reporting, as well as over-current protection.

Applications include server, cloud, networking, telecom, and storage systems, as well as distributed point-of-load power architectures and DDR memory.
