General description
The RC5057 is a synchronous mode DC-DC
controller IC which provides a highly accurate,
programmable output voltage for all Pentium II
& III CPU applications and other high-
performance processors. The RC5057 features
remote voltage sensing, adjustable current
limit, and active droop for optimal converter
transient response. The RC5057 uses a 5-bit
D/A converter to program the output voltage
from 1.3V to 3.5V. The RC5057 uses a high
level of integration to deliver load currents in
excess of 16A from a 5V source with minimal
external circuitry. Synchronous-mode
operation offers optimum efficiency over the
entire specified output voltage range. An on-
board precision low TC reference achieves
tight tolerance voltage regulation without
expensive external components, while active
droop permits exact tailoring of voltage for the
most demanding load transients. The RC5057
also offers integrated functions including
Power Good, Output Enable/Soft Start and
current limiting, and is available in a 16 pin
SOIC package.
