LX1670 Overview
The LX1670 is a plete 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.
