Input Stability Calculator

This spreadsheet was created from the inequality tests in the Input System Instability Application Note.  It is intended to help the user select the proper components to insure stability of the system input stage.

Trim Resistor Calculator

This spreadsheet tool quickly calculates trim resistor values for various SynQor modules.  An alternate method to trim output voltages is to provide a voltage at the trim pin and this voltage is also calculated for you.  Use this tool to quickly find the appropriate resistor value and then validate the output voltage using your own standard resistor value.  A schematic of the trim input circuit is provided to better understand how the converter uses a resistor or voltage input at the trim pin.
