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 gener-
ate 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 on-
board 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 oscil-
lator can be programmed to operate over a range of 200KHz
to 1MHz to allow flexibility in choosing external compo-
nents.
