GENERAL DESCRIPTION
1
5 Bit Programmable Synchronous Buck
Converter with Dual LDOs Controller
NIKO-SEM
N1164
AUG-03-2001
The N1164 is a 5 bit TTL-compatible input,
digital-to-analog (DAC) programmable, syn-
chronous buck converter with dual LDOs
controller designed specifically to power the
Pentium
II as well as the next generation of
P6 family or other high performance core
logic in desktop personal computer and file
servers CPU applications.
The N1164 switching section provides pro-
grammability of output voltage from 1.3V to
2.05V in 50mV steps and 2.0V to 3.5V in 100
mV increments and the linear sections use
external N-Channel power MOSFETs to
provide fixed output voltages of 1.5V for GTL
bus and 2.5V for clock.
The N1164 monitors all the output voltages.
A signal Power-Good signal is issued when
the core is within
±
15% of the DAC setting.
Additional features are built-in over-voltage,
over-current protections for the core output
and logic compatible shutdown.
