Description of product: Pololu D24V3F3 Converter step-down 3.3 V 0.3 A

Converter type step-down is used to power the systems operating voltages of 3.3 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 5 and more maximum load current up to 600 mA.

The output of the Converter D24V3F3

The module has four output output:

  • VIN - input voltage range 3.8 V to 42 V, it is necessary to pay attention to the value of drop-out and short voltage pulses, which can damage the system
  • GND - the ground
  • VOUT- output voltage
  • SHDN is used to indicate the status of the low level (logical zero) causes the system to low power state (approx. 20 uA). To run the system, you must specify the high state (logical unit - voltage above 2.3 V). If the output is not being used, you can combine it with an adjacent terminal VIN.

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.

 

On request, we can provide the model with zlutowanymi senior goldpin. For this purpose, please leave the details in comments to the order.

The serviceability of the Converter

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 %.

   

Voltage Cut-Off

The parameter is specified 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 should be higher than 6 V. the figures below show the voltage drop-out for converters D24VxFx.

Hazardous voltage pulses

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.
