Converter type step-down is used to power the systems operating voltage 5 V Car system is the wide input voltage range from 3.8 V to 42 V (the minimum value depends on the voltage drop-out). The module allows the current consumption to 300 mA is enough value to power ordinary integrated circuits. In our offer we have also version for 3.3 V and maximum load current to 600 mA.
The module has four output output:
Connectors respectively signed on the Board. Terminal pitch is 2.54 mm (popular goldpin connectors). The module can be mounted on the contact plate, to connect with wires or solder in a special printed circuit Board.
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 parameter stated in the documentation as a drop-out voltage is necessary for the proper operation of the system, the minimum difference between input voltage and output. For example, if drop-out is 1 Volt, and preferably the output voltage is 5 V, the voltage supply must be higher than 6V. The figures below show the voltage drop-out for converters D24VxFx.
When connecting power to the module, can appear dangerous, eclectic short pulses of high amplitude (so-called pins), which can damage the system. Test company, Pololu, it follows that for voltages above 20V studs can have an amplitude in excess of 42V. 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.
