Summary
AN-84 describes a tool (TST-047) which enables test and debug of InnoSwitch3-Pro
based power supplies.
The TST-047 enables a set of operating conditions to be programmed into the
InnoSwitch3-Pro IC. Once programmed, these settings are stored in a Non-volatile
memory and are automatically transferred to the InnoSwitch3-Pro IC whenever the
power is cycled. This allows testing of the InnoSwitch3-Pro based power stage without
the need for an external Microcontroller.
This tool is especially helpful when repeated tests are to be performed such as EMI or
safety tests and the InnoSwitch3-Pro based power stage is to be set to a specific
operating point. This is useful when conducting thermal tests or tests where the unit is
being modified and there is a need for the InnoSwitch3-Pro to get configured with a
specific set of parameters after each power cycle.
