TYPICAL APPLICATION
Pentium Dual Supply Application
Figure2- Typical application of US3033 in a flexible motherboard with the 4 bit VID output voltage selection. This circuit uses
a single jumper that programs the output voltage in 16 steps with 0.1V steps from 2V to 3.5V, designed for Intel P55
,P54
, AMD K5
& K6
as well as Cyrix M1
and M2
applications. The Vcc2Det pin automatically shuts down the I/O regulator when a single plane
processor is dropped in the socket.
