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.

FEATUREs
• Programmable output for Vcore from 1.3V to 3.5V using an integrated 5-bit DAC
• Controls adjustable linears for Vtt (1.5V), and Vclock (2.5V)
• Meets VRM specification with as few as 5 capacitors
• Meets 1.550V +40/-70mV over initial tolerance, temperature and transients
• Remote sense
• Active Droop (Voltage Positioning)
• Drives N-Channel MOSFETs
• Overcurrent protection using MOSFET sensing
• 85% efficiency typical at full load
• Integrated Power Good and Enable/Soft Start functions
• 20 pin SOIC package

APPLICATIONs
• Power supply for Pentium® III Camino Platform
• Power supply for Pentium III Whitney Platform
• VRM for Pentium III processor
• Programmable multi-output power supply
