VRM10.0 COMPLIANT PROGRAMMABLE FEEDBACK DIVIDER

FEATURES

DESCRIPTION

•

VRM 10.x VID Code Table

14-Pin TSSOP

The TPS40120 is a 6-bit digitally programmed

feedback divider designed to work with TPS40090

multiphase controller or other controllers having 0.7-V

internal reference to support VRM 10.x compliant

power supplies. The TPS40120 is designed to sup-

port discrete DC/DC converters for Intel^®processors

using 5-bit (Pentium^®4 or Xeon™) or 6-bit VID codes

with 12.5 mV steps.
