• 2574 - PAC Designer: Is it possible to manually assign TRIM DAC output voltages to Power Manager II Devices, rather than using the trim configuration calculator?

  Solution:It is possible to assign manual DAC codes to the different profiles of the Power Manager II TRIM DAC outputs. The menu interface for manual assignment can be found in the Edit->Symbol menu in the top level schematic view of PAC-Designer. The ...

• 2586 - PAC Designer: In the PAC-Designer TRIM block, why does the Vbpz value sometimes change when the EIA Resistor Standard is changed in the options menu?

  Solution: The EIA resistor standard option sets the available resistor choices to the TRIM calculator. For example, EIA96 gives more resistor choices to the calculator then EIA24. The calculator compares the possible Vbpz values with different ...

• 2449 - PAC Designer; L-ASC10: During Trim configuration in PAC-Designer, I receive an error when calculating DAC settings for my target profiles. What can cause this?

  Solution:The Trim calculation references settings which can be configured in the Trim Configuration Options menu. In some cases you can fix the errors by increasing the "Maximum Supply Adjustment Range" from the default value of 5%. In other cases, ...

• 2848 - PAC Designer Trim Configuration: if the Profile0 mode is changed from Closed Loop Trim (CLT) to I2C, does the calculated value of resistors change?

  In the Trim Configuration of PAC-Designer software for the Profile0 Mode, the calculated value of resistors remains the same regardless of whether I2C or CLT is used. To have the correct resistor network between POWR1220AT8 and the DC-DC converter, ...
