Description
The RC5051 is a synchronous mode DC-DC controller IC which provides an accurate, programmable output voltage for all Pentium II CPU applications. The RC5051 uses a 5-bit D/A converter to program the output voltage from 1.3V to 3.5V. The RC5051 uses a high level of integration to deliver load currents in excess of 19A from a 5V source with minimal external circuitry. Synchronous-mode operation offers optimum efficiency over the entire specified output voltage range, and the internal oscillator can be programmed from 80KHz to 1MHz for additional flexibility in choosing external ponents. An on-board precision low TC...
