Product Summary

The RT8284NGS is a high efficiency, monolithic synchronous step down DC/DC converter that can deliver up to 2A output current from a 4.5V to 23V input supply. The RT8284NGS’s current mode architecture and external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. The applications of the RT8284NGS include Wireless AP/Router, Set-Top-Box, Industrial and Commercial Low Power Systems, LCD Monitors and TVs, Green Electronics/Appliances, Point of Load Regulation of High-Performance DSPs.
