7 / 32 page ADP3197 Rev. 0 | Page 7 of 32 Pin No. Mnemonic Description 21 to 23 PWM3 to PMW1 Logic Level PWM Outputs. Each output is connected to the input of an external MOSFET driver, such as the ADP3120. Connecting the PWM3 output to VCC causes that phase to turn off, allowing the ADP3197 to operate as a 2-phase or 3-phase controller. 24 VCC A 340 Ω resistor should be placed between the 12 V system supply and the VCC pin. The internal shunt regulator maintains VCC = 5 V. 25 to 30 VID5 to VID0 Voltage Code DAC Inputs. These six pins are pulled down to GND, providing a Logic 0 if left open. When in normal operation mode, the DAC output programs the FB regulation voltage from 0.3750 V and 1.55 V (see Table 4). 31 TTSENSE VR Hot Thermal Throttling Sense Input. An NTC thermistor between this pin and GND is used to remotely sense the temperature at the desired thermal monitoring point. 32 VRHOT Open-Drain Output. This output signals when the temperature at the monitoring point connected to TTSENSE exceeds the maximum operating temperature. This can be connected to the PROCHOT# (a PC system signal) output from the CPU. |
