5 Bit Programmable Synchronous
Buck Converter with Dual LDOs
N3004
GENERAL DESCRIPTION
The N3004 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 N3004 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 N3004 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.
FEATURES
z Synchronous operation with high efficiency
z TTL-compatible 5 bit DAC, output voltage
selection from 1.3V to 3.5V programmable
z Fast transient response
z Provides 2 regulated voltages, 1.5V and
2.5V for linear section
z Power-Good output voltage monitor
z Over-Voltage and Over-Current protection
z Logic level enable input
z High performance and low cost solution
APPLICATIONS
z Powering Pentium, ® II, III or Deschutes,
K6 and other advanced processor
z High power DC to DC controller with triple
output supplies
