DESCRIPTION

The LX1670 is a complete precision

reference and voltage monitor circuit

for the Intel Pentium

廬

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.
