A precise 6-bit digital to analog converter (DAC) allows adjusting the output voltage from 0.8375V to 1.6000V with 12.5mV binary steps managing Dynamic VID code changes. The high precision internal reference assures the selected output voltage to be within 0.5% over line and temperature variations. The high peak current gate drive affords to have fast switching to the external power mos providing low swit...
