Negatron DC-DC Converter
Negatron is a buck-boost converter that takes a positive voltage and turns it into a negative voltage that you can use with amplifier circuits and more.
The output is adjustable from -1.3V to -12V. Negatron is also able to step up/step down the magnitude of the voltage. For example, you can feed Negatron +9V and it can give you a -5V or a -12V rail.
Negatron is the perfect choice for engineers frustrated with trying to create a negative voltage source in their low power circuit.
Negatron will operate from a 4V to 14V input and the output voltage is set with the small screw potentiometer on the top.
Negatron is pin-compatible with the common 78XX series of linear voltage regulators, so it will work with breadboards and other popular prototyping methods.
Negatron is very different from any other DC-DC converter on the market so please read the entire datasheet thoroughly before buying or using one.
