RC5058 General Description
The RC5058 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 RC5058 features remote voltage sensing, independently adjustable current limit, and a proprietary Programmable Active Droop ™ for optimal converter transient response. The RC5058 uses a 5-bit D/A converter to program the output voltage from 1.3V to 3.5V. The RC5058 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 Programmable Active Droop ™ permits exact tailoring of voltage for the most demanding load transients. The RC5058 includes linear regulator controllers for Vtt termination (1.5V), Vclock (2.5V), and Vnorthbridge (1.8V) or Vagp (selectable 1.5V/3.3V), each adjustable with an external divider. The RC5058 also offers integrated functions including Power Good, Output Enable/Soft Start and current limiting, and is available in a 24 pin SOIC package.
