The device embeds selectable DAC: the output voltage ranges from 0.8185V to 1.5810V with 12.5mV steps (VID_SEL = OPEN) or from 0.800V to 1.550V with 25mV steps (VID_SEL = GND; VID5 drives an optional +25mV offset) managing dynamic VID with 0.5% accuracy over line and temp variations. Additional programmable offset can be added to the voltage reference with a single external resistor. The device assures a fast protection against load over current and load over/under voltage. An internal crowbar is provided turning on the low...
