DESCRIPTION
The L5995 is a power supply controller that offers
a complete power management for
CPUs of the next generationespecially for mobile
Pentium II. A high precise 4 bit digital to analog
converter (DAC) allows to adjust the output volt-
age from 1.3V to 2.0V with 0.05V binary steps.
The high precision internal reference, digitally
trimmed, assures the selected output voltage to
