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-perfor-
mance 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 cur-
rents in excess of 16A from a 5V source with minimal exter-
nal 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.
