DESCRIPTION
The L5996 is a power supply controller that offers
a complete power management for
notebook
CPUs of the next generation especially for mobile
Pentium III. A high precise 5 bit digital to analog
converter (DAC) allows to adjust the output volt-
age from 0.925V to 2.0V. Dynamic DAC code
changes are detected on chip in order to switch
the output voltage between 1.3V and 1.45V in
less tahn 100
