2.2.4 Margin Up/Down (J4)

The margin up and down feature of the EVM provides the user with the ability to trim or margin the output of the converter up/down by 3% or 5%. The EVM is equipped with convenient jumper settings to give the user the ability to trim the output voltage. Please see Section 5.3.5 for more detailed test setup information.
