1. It's different. 2. This is because different pins perform different functions in circuit design and need to provide different voltages. The sd6834 power supply chip usually has multiple pins, some of which may provide positive voltage, some of which may provide negative voltage, and some of which may provide ground or other specific voltages.
Specific voltage values need to refer to the technical specifications of the chip or related materials.
Sorry, it is not possible to answer the question accurately based on the information provided. The SD6834 is a power supply chip model, but no specific pin definitions or chip specifications are provided to determine the voltage of each pin. It is recommended to provide more details or refer to the relevant chip manual for an accurate answer.
7 pin 16V voltage, 8 pin output 5V voltage.
