Guaranteed by design. Not tested in production. PACKAGE PIN DESCRIPTION PACKAGE PIN # PIN SYMBOL FUNCTION 28 Lead SO Wide 1 COMP Output of the error amplifier and input for the PWM comparators. 2 VFB Voltage Feedback Pin. To use Adaptive Voltage Positioning (AVP) select an offset voltage at light load and connect a resistor between VFB and VOUT. The input bias current of the VFB pin and the resistor value determine output voltage off- set for zero output current. Short VFB to VOUT for no AVP. 3 VDRP Current sense output for AVP. The offset of this pin above the DAC voltage is proportional to the output current. Connect a resistor from this pin to VFB to set amount AVP or leave this pin open for no AVP. 4−5 CS1−CS2 Current sense inputs. Connect current sense network for the corresponding phase to each input. 6 CSREF Reference for current sense amplifiers and input for Power Good comparators. To balance input offset voltages between the inverting and non−inverting inputs of the current sense amplifiers, connect a resistor between CSREF and the output voltage. The value should be 2/5 of the value of the resistors connected to the CSx pins. 7 PWRGD Power Good Output. Open collector output goes low when CSREF is out of regulation. |
