Low = single phase operation; High = normal operation 3 VID0 Voltage ID DAC input 4 VID1 Voltage ID DAC input 5 VID2 Voltage ID DAC input 6 VID3 Voltage ID DAC input 7 VID4 Voltage ID DAC input 8 VID5 Voltage ID DAC input 9 VID6 Voltage ID DAC input 10 VID7/AMD Voltage ID DAC input. Pull to VCC (5 V) to enable AMD 6−bit DAC code. 11 ROSC A resistance from this pin to ground programs the oscillator frequency and provides a 2 V reference for programming the ILIM voltage. 12 ILIM Over current shutdown threshold setting. ILIM = VDRP − 1.3 V. Resistor divide ROSC to set threshold 13 IMON 0 to 1.1 V analog signal proportional to the output load current. VSN referenced Clamped to 1.1 Vmax 14 VSP Non−inverting input to the internal differential remote sense amplifier 15 VSN Inverting input to the internal differential remote sense amplifier 16 DIFFOUT Output of the differential remote sense amplifier 17 COMP Output of the compensation amplifier 18 VFB Compensation amplifier voltage feedback 19 VDRP Voltage output signal proportional to current used for current limit and output voltage droop 20 VDFB Droop Amplifier Voltage Feedback 21 CSSUM Inverted Sum of the Differential Current Sense inputs 22 DAC DAC output used to provide feed forward for dynamic VID 23 12VMON Monitor a 12 V input through a resistor divider 24 VCC Power for the internal control circuits with UVLO monitor 25 CS4P Non−inverting input to current sense amplifier #4 26 CS4N Inverting input to current sense amplifier #4 27 CS3P Non−inverting input to current sense amplifier #3 28 CS3N Inverting input to current sense amplifier #3 29 CS2P Non−inverting input to current sense amplifier #2 30 CS2N Inverting input to current sense amplifier #2 31 CS1P Non−inverting input to current sense amplifier #1 32 CS1N Inverting input to current sense amplifier #1 33 EN Threshold sensitive input. High = startup, Low =shutdown. 34 VR_RDY Open collector output. High indicates that the output is regulating 35 G4 PWM output pulse to gate driver. 36 BG1 Low side gate drive #1 37 BST1 Upper MOSFET floating bootstrap supply for driver#1 38 TG1 High side gate drive #1 39 SWN1 Switch Node #1 40 VCCP Power VCC for gate drivers with UVLO monitor 41 BG2 Low side gate drive #2 42 SWN2 Switch Node #2 43 TG2 High side gate drive #2 44 BST2 Upper MOSFET floating bootstrap supply for driver#2 45 DRVON Bidirectional Gate Drive Enable 46 SWN3 Switch Node #3 47 TG3 High side gate drive #3 48 BST3 Upper MOSFET floating bootstrap supply for driver#3 FLAG GND Power supply return (QFN Flag) |
