RC5041 General Description

The RC5041 is a non-synchronous DC-DC controller IC which provides an accurate, programmable output for Pentium CPU applications. Using an integrated 4-bit DAC to accept a voltage identification (VID), the RC5041 can generate precise output voltages between 2.1V and 3.5V in 100mV increments. Output load currents in excess of 10A can be delivered using minimal external circuitry. The RC5041 is designed to operate in a standard PWM control mode under heavy load conditions and in PFM control mode while supplying light loads for optimal efficiency. An onboard precision low TC voltage reference eliminates the requirement for external components in order to achieve tight voltage regulation. The Pentium CPU is continuously protected by an integrated Power Good function, which sends an active-low interrupt signal to the CPU in the event that the output voltage is out of tolerance. The internal oscillator can be programmed to operate over a range of 200KHz to 1MHz to allow flexibility in choosing external components.
