pin Functions
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-
PGOOD1 and PGOOD2 (A11 and G11):
Output Voltage plications Information section. Power Good Indicator for Each Channel. Open-drain logic
FB1 and FB2 (D8 and K8):
The Negative Input of the Error output that is pulled to ground when the output voltage Amplifier for Each Channel. Internally, this pin is connected is not within ±10% of the regulation point. Power good to VOUT with a 10k precision resistor. Different output is disabled during margining. voltages can be programmed with an additional resistor
RUN1 and RUN2 (F6 and M6):
Run Control Pin. A voltage between FB and GND pins. In PolyPhase® operation, tying above 1.7V will turn on the module. the FB pins together allows for parallel operation. See the Applications Information section for details.
SW1 and SW2 (B6 and H6):
Switching Node of Each Channel That is Used for Testing Purposes. This can be
ITH1 and ITH2 (F8 and M8):
Current Control Threshold and connected to an electronically open circuit copper pad on Error Amplifier Compensation Point for Each Channel. The the board for improved thermal performance. current comparator threshold increases with this control voltage. Tie together in parallel operation.
CLKOUT1 and CLKOUT2 (F7 and M7):
Output Clock Signal for PolyPhase Operation. The phase of CLKOUT is
ITHM1 and ITHM2 (E7 and L7):
Negative Input to the Internal determined by the state of the PHMODE pin. ITH Differential Amplifier for Each Channel.
