already low. Do not float this pin. A resistor and capacitor SGND for single phase operation on each channel. For can be applied to the TRACK pin to increase the soft-start PolyPhase operation, tie the master’s ITHM to SGND while time of the regulator. TRACK1 and TRACK2 can be tied connecting all of the ITHM pins together at the master. together for parallel operation and tracking. See the Ap-
