ISL6552
ISEN1, ISEN2, ISEN3 and ISEN4
Current sense inputs from the individual converter channel’s
phase nodes. Unused sense lines MUST be left open.
PGOOD
Power good. This pin provides a logic-high signal when the
microprocessor CORE voltage (VSEN pin) is within specified
limits and Soft-Start has timed out.
VCC
Bias supply. Connect this pin to a 5V supply.
