DESCRI PTI O N
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.
