The TST-047 enables a set of operating conditions to be programmed into the InnoSwitch4-Pro IC. Once programmed, these settings are stored in a Non-volatile memory and are automatically transferred to the InnoSwitch4-Pro IC whenever the power is cycled. This allows testing of the InnoSwitch4-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 InnoSwitch4-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 InnoSwitch4-Pro to get configured with a specific set of parameters after each power cycle.

This manual is describes what constitutes the toggle board, how it works and how to use it with InnoSwitch4-Pro family of devices. It also contains the schematic, bill of materials, printed circuit board layout.
