5 Bit Programmable Power Supply Controller For Pentium Ii Processor

The L6911B is a power supply controller specifi- cally designed to provide a high performance DC/DC conversion for Pentium II Microproces- sors. A precise 5 bit digital to Analog converter (DAC) allows to adjust the output voltage from 1.3V to 2.05V with 0.05V binary steps and from 2.1V to 3.5V with 0.1V binary steps. The high pre- cision internal reference, digitally trimmed, as- sures the selected output voltage to within +/-1%. Thanks to the window Comparator system, the de- vice provides excellent load transient perform- ance. The high peak current Gate drive affords to have fast switching to the external power mos, performing an high efficiency. The L6911B as- sures a fast protection against load overvoltage and load overcurrent. An external SCR is trig- gered to crowbar the input supply in case of over- voltage. In case of output short circuit the soft start capacitor is discharged and the system works in hiccup mode. By STMicroelectronics
