RC5051 - Programmable Synchronous DC-DC Controller for Low Voltage Microprocessors

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.

Features

  • Programmable output from 1.3V to 3.5V using an integrated 5-bit DAC.
  • 85% efficiency typical.
  • Adjustable operation from 80KHz to 1MHz.
  • Integrated Power Good and Enable functions.
  • Overvoltage protection.
  • Overcurrent protection.
  • Drives N-channel MOSFETs.
  • 20 pin SOIC package.
  • Meets Intel Pentium II specifications using minimum number of external components.
