The L5995 is a power supply controller that offers a complete power management for notebook CPUs of the next generation especially for mobile Pentium II. A high precise 4 bit digital to analog converter (DAC) allows to adjust the output voltage from 1.3V to 2.0V with 0.05V binary steps. The reference can be programmed with an auxiliary bit between 2.1V and 3.5V with 0.1V steps. The high precision internal reference, digitally trimmed, assures the selected output voltage to within +/-1% over temperature and battery voltage variations. Thanks to the remote sensing inputs and to the window comparator system, embedded in the error summing structure,L5995 provides excellent load transient performance. The high peak current gate drive affords to have fast switching to the external power mos, performing an high efficiency. A complete power management include on board a programmable power-up sequencing, power good signal, skip mode operation and undervoltege detection. The L5995 assures a fast protection against load overvoltage and load overcurrent. Linear regulator on-board is available with an output voltage of 2.5V (+/-2%) and a current capability of 150mA, useful for CPU CLOCKBUS.
