12 volt to 1.5V, 3V, 5V, 6V, 7.5V, 9V Volt DC/DC Converter

Adjustable Voltage Regulator

This "buck converter" or voltage-reducing DC/DC converter is designed to power CD players, walkmans, video games, portable TVs, tape recorders, GPS, hand scanners, and radios from automobile cigarette lighter power points.

It is an extremely reliable, full switchmode power supply. These are used extensively as OEM regulating power supplies when 6 to 30 volts is available, and a reduction in voltage is required.

This product has been extensively tested and approved by PowerStream Engineers

These are consumer devices, but are used in many OEM and engineering applications due to their low cost and high reliability. They are used in heavy equipment, cell phone towers, microwave towers, and many other places.

Price $18.95 each

*Note: Devices using batteries can accept a wide range of input voltages, for example alkalines vary between 1.5 and 1 volt per cell during discharge. This guideline takes this into account. Also most wall-mount adapters are unregulated. So select the closest to your nominal voltage and don't worry about finding the exact voltage.

**Although the 12 volt setting requires 14 volts to stay regulated, the 13.6 volts supplied by a car battery even when the car is off will supply over 11.5 volts, will be adequate for most 12 volt devices.

Advantages:

Inexpensive switchmode DC/DC converter stabilizes voltage in automotive applications.

Also can be used to provide regulated voltage in other applications requiring 1.5 to 12 volt output from 8 to 30 volt input.

Efficiency >50-80%, depending on input, output, and power.
