RC5058
Overview
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.
- Programmable output for Vcore from 1.3V to 3.5V using an integrated 5-bit DAC
- Controls adjustable linears for Vagp (selectable 1.5V/3.3V), Vclock (2.5V), and Vtt (1.5V) or Vnorthbridge (1.8V)
- Meets VRM specification with as few as 5 capacitors
- Meets 1.550V +40/-70mV over initial tolerance, temperature and transients * * * * * *
