RC5058 - High Performance Programmable Synchronous DC-DC Controller for Multi-Voltage Platforms

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.

Features

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.
Remote sense Programmable Active Droop™ (Voltage Positioning) Drives N-Ch.
