12 volt to 1.5V, 3V, 4.5V, 6V,
7.5V, 9V Volt DC/DC Converter (Adjustable Voltage Regulator) |
|
|
This "buck," 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.
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. |

*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. |
