RC5050 General Description

The RC5050 is a DC-DC controller IC which provides an accurate, programmable output for all Pentium II CPU applications. The RC5050 uses a 5-bit D/A converter to program the output voltage from 1.3V to 3.5V. The RC5050 uses a high level of integration to deliver load currents in excess of 15A from a 5V source with minimal external circuitry. Nonsynchronous operation allows a low cost solution for most CPU power supply applications. The internal oscillator can be programmed from 80KHz to 1MHz for additional flexibility in choosing external components. An on-board precision low TC reference achieves tight tolerance voltage regulation without expensive external components. The RC5050 also offers integrated functions including Power Good, Output Enable, over-voltage protection and current limiting.
