In order to work with both a 12V and a 9V input, you will need to use the buck-boost topology. This should allow the regulator to both step up the voltage if the input is lower than the required output voltage, or step it down if the input is higher (or equal).
Can I run a 9V device on 12V?
If you have a 12V adapter, you might wonder whether you can use it to power your 9V guitar pedals. In most cases, you cannot use a 12V adapter to power a 9V guitar pedal. Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it.
How can I make a simple voltage booster?
Basically, DC-DC converters/boosters are electronic circuits that step up or step down the DC voltage to get the desired voltage level.

Can I use a 9V power supply on a 12V router?
However, the 9 Volt router cannot be run on the 12 Volt UPS. The 9 Volt router is meant to be run on 9 Volts and attempting to power it with the 12 Volt UPS will result in an overvoltage thus permanently damaging the router. No, it will not be possible to do that.
Can I use 9V adapter for 12V router?
You cannot use that adapter because it is outputting more voltage than the original (12v vs. 9v). This has a likely chance of burning out one or more of the components within the router.
How do you increase voltage?
To increase the voltage, we connect the AC voltages in series to get a higher output voltage. If the frequency of all the voltages are the same, the magnitude of the voltages simply add. The voltages will just add, so the total voltage will be 28Vac at 60Hz.
How do I increase the voltage of my battery?
In order to increase the voltage between a battery’s terminals, you can place the cells in series. Series means stacking the cells end-to-end, connecting the anode of one to the cathode of the next. By connecting batteries in series, you increase the total voltage.
How do you increase DC amps?
A decrease in the resistance results in an increase in the amperes. Therefore, by increasing the voltage in a circuit or by decreasing the resistance in a circuit, the amperes in a circuit will be increased.
Can you increase the voltage output?
DC voltage can be also increased by using the voltage multiplier circuit. The Voltage Multiplier is a type of diode rectifier circuit which can produce an output DC voltage many times greater than of the applied AC input voltage. The AC voltage can be raised by using the step-up transformer.
When should I use boost converter?
The boost converter is used to “step-up” an input voltage to some higher level, required by a load. This unique capability is achieved by storing energy in an inductor and releasing it to the load at a higher voltage.
How do you convert 9V dc to 5V DC?
A 9v to 5v voltage regulator can be implemented with an LM7805 step-down voltage converter. It is used for (10mA to 1 Amp and more) medium to the high current application. The unique about this circuit is its ability to provide the same output current as applied at the input end.
How do you multiply voltage on a battery?
When connecting your batteries in Series you are doubling the voltage while maintaining the same capacity rating (amp hours). This might be used in a scooter, Power Wheels kids vehicle, or other applications. Just use a jumper wire between the negative of the first battery and the positive of the second battery.
Can I charge a 9V battery with a 5V charger?
You would not be able to charge a 9V with a 5V source. You can still charge that battery till 5V but once you cross that current will start flowing from the battery back to the source.
What happens if I use A 9V adapter on A 12V device?
Plugging in an adapter with a lower voltage would not generally harm the unit. But if the polarity is reversed then it probably would cause damage and that may be what has happened. It may just have blown a fuse.
Can I use 12V 1A for 9V 0.6 A?
No, a 12V Adapter provides too high a voltage for the intended application (9V).
Can I use 12V 1A for 9V 1A?
Yes you can. Just add a 12V, 1A regulator like a LM 7812 in series.
Can I use 9V Charger for 12V?
You cannot use a 9 volt charger as it will not be capable of providing enough voltage. A 12 volt battery (I’m using a lead-acid battery as an example) needs a charging voltage of about 13.5 volts to properly charge the battery.
Can I use any 9V adapter?
– Yes, they are likely interchangeable even though voltage is not the same. This is because the voltage difference is within specs, and I am GUESSING you could go even higher or lower in voltage.
Can I use 5v adapter for 9V?
No! It might work for few minutes, but eventually the voltage drop on the internal regulator will cause the circuit to overheat and burn.
How can you increase voltage without changing current?
In order to change the voltage without changing the current, you must change the resistance a porportional amount. If the load resistance varies, you can use a constant current source to maintain the current level, as hgmjr implied.
How do you fix low voltage?
Once you discover a low voltage electrical outlet, unscrew the plate and locate the ground, neutral and hot voltage wires. Tighten the screws that hold these wires in place. This might fix your issue. If any of the wires look corroded, strip them until you see shiny copper and clean the connections.
