Voltage Regulation and Load Line
Implementation
After the start sequence, the ISL62883 regulates the
output voltage to the value set by the VID inputs per
Table 1. The ISL62883 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.
