Description of product: Pololu U3V12F12 Converter, step-up, 12V 1.4 A

The regulator increases the voltage from 2.5 to 12 Volts to a constant value of 12 V. the Efficiency of the Converter is 80 - 90% depending on input voltage. In our offer also modules of this series with output voltage of 5 Volts, 9 Volts and 12 Volts.

The output of the Converter U3V12F12

The module has three pins:


Connectors respectively signed on the Board. Terminal pitch 2.54 mm is a popular connectors goldpin, allow for installation of the module on the Board contact or connect using wires.


Efficiency is defined as the ratio of output power to input power (Power out)/(Power in). This is a very important parameter for portable sources of energy (batteries and accumulators), which has a value of working time on one cycle charging. The efficiency of the system pulse is about 80% - 90%. The output current depends on input voltage. Details are available in the diagram:


The serviceability and output current at an output voltage of 12V.

Hazardous voltage pulses

When connecting power to the module, can appear dangerous, eclectic short pulses of large amplitude (called studs) that can damage the system. Test company, Pololu, it follows that for voltages above 10V studs may have the amplitude exceeding 20V. To protect against this undesirable phenomenon wlutowanie recommended capacitor value of at least 33uF as close as possible to the power pins of the Converter.
