They sit at 5 V until a device requests something higher over the configuration channel. This module performs that request on your behalf and then holds it, so the charger keeps supplying the selected voltage indefinitely.\u003c\/p\u003e\n\u003cp\u003eNegotiation is handled by a PAK02A trigger IC, with an HT7550-1 linear regulator dropping the output rail down to a stable 5 V for the chip's own logic supply. That is the entire signal path, so nothing on the board sits between the charger and your load.\u003c\/p\u003e\n\u003cp\u003eBecause it is a trigger rather than a converter, it does not boost, buck or regulate. The output is whatever the charger provides, passed straight through. That means very high efficiency and no switching noise added by the module, but it also means the charger must genuinely support the voltage you select.\u003c\/p\u003e\n\u003ch2\u003eQuick start\u003c\/h2\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet the DIP switch\u003c\/strong\u003e to the voltage you want, using the table printed on the back of the board.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePlug in the charger\u003c\/strong\u003e with a USB-C cable.

Why?\u003c\/h3\u003e\n\u003cp\u003eThree usual causes: the charger does not actually support 9 V, the DIP switch is not making solid contact, or the switch combination is not one of the valid entries in the table.
