Description

The FAN5093MTCC is a synchronous two-phase DC-DC controller IC designed for VRM 9.x processors. It provides a highly accurate and programmable output voltage with a wide range of integrated functions, eliminating the need for external devices. With its fast transient response and high integration, this model can deliver load currents in excess of 50A from a 12V source with minimal external circuitry. It is available in a 24 pin TSSOP package.
