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 voltage 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 100µs.
