The LX1670 is a complete precision
reference and voltage monitor circuit
for the Intel Pentium
Pro Processor
and other high-end microprocessor
supplies. It is designed for use in
conjunction with the LX1660/1661 PWM
controller. The LX1670 reads a 5-bit
voltage identification (VID) code from
the microprocessor and sets the output
voltage reference to be used by the
LX1660/61 controller. Together, they
convert +5 or 12V input power to an
adjustable output ranging from 1.8VDC
to 3.5VDC in 100mV steps (50mV steps
below 2.1V) with 1% DC system
accuracy.
