The ISL6556A utilizes r DS(ON) current sensing in each phase for adaptive voltage positioning (droop), channelcurrent balancing, and over-current protection. To ensure droop accuracy, an external NTC compensation circuit can be used to completely nullify the effect of temperature related variation in rDS(ON) . A unity gain, differential amplifier is provided for remote voltage sensing. Any potential difference between remote and local grounds can be eliminated using the remote-sense amplifier. The precision threshold-sensitive enable input is available to accurately coordinate the start up of the ISL6556A with Intersil MOSFET driver IC. Dynamic-VIDTM technology allows seamless on-the-fly VID changes. The offset pin allows accurate voltage offset settings that are independent of VID setting. The ISL6556A uses 5V bias and has a built-in shunt regulator to allow 12V bias using only a small external limiting resistor.
