RC5061

The RC5061 is a synchronous mode DC-DC controller IC which provides a highly accurate, programmable set of output voltages for multi-voltage platforms such as the Intel Camino, and provides a complete solution for the Intel Whitney and other high-performance processors. The RC5061 features remote voltage sensing, independently adjustable current limit, and Active Droop for optimal converter transient response. The RC5061 uses a 5-bit D/A converter to program the output voltage from 1.3V to 3.5V. The RC5061 uses a high level of integration to deliver load currents in excess of 16A from a 5V source with minimal external circuitry. Synchronous-mode operation offers optimum efficiency over the entire specified output voltage range. An on-board precision low TC reference achieves tight tolerance voltage regulation without expensive external components, while Active Droop permits exact tailoring of voltage for the most demanding load transients. The RC5061 includes linear regulator controllers for Vtt termination (1.5V), and Vclock (2.5V), each adjustable with an external divider. It also offers integrated functions including Power Good, Output Enable/Soft Start and current limiting, and is available in a 20 pin SOIC package.
