specifications. It responds to PSI# and DPRSLPVR signals by adding or dropping Phase 2, adjusting overcurrent
protection threshold accordingly, and entering/exiting diode emulation mode. It reports the regulator output current
through the IMON pin. It senses the current by using either discrete resistor or inductor DCR whose variation over
temperature can be thermally compensated by a single NTC thermistor. It uses differential remote voltage sensing to
accurately regulate the processor die voltage. The unique split LGATE function further increases light load efficiency.
The adaptive body diode conduction time reduction function minimizes the body diode conduction loss in diode
emulation mode. User-selectable overshoot reduction function offers an option to aggressively reduce the output
capacitors as well as the option to disable it for users concerned about increased system thermal stress. The
ISL62882C offers the FB2 function to optimize 1-phase performance.
