Description

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.
