Voltage Regulation and Load Line
Implementation
After the start sequence, the ISL62881 regulates the output
voltage to the value set by the VID inputs per Table 1. The
ISL62881 will control the no-load output voltage to an accuracy of
±0.5% over the range of 0.75V to 1.5V. A differential amplifier
allows voltage sensing for precise voltage regulation at the
microprocessor die.
