描述 Description

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.
