Polyole D24V3AHV - 4 V - 25 V step-down converter 0.3 A

The module has four outputs:

  • VIN - input voltage,
  • GND - mass potential,
  • VOUT - output voltage,
  • SHDN - system shutdown.

If the SHDN pin shows a low state (below 0.3 V), the inverter is switched off and the current consumption does not exceed 20 uA. If the high state (above 2.3 V) appears on the SHDN pin, the system will be activated again. The output can be permanently connected to the VIN or left unconnected if the shutdown mode is not used.

The connectors are properly signed on the board. The output roster is 2.54 mm (popular goldpin connectors). The module can be plugged into a contact board , connected with wires or soldered into a dedicated PCB .

Output voltage is determined by means of a potentiometer. Setting the voltage higher than input will not damage the system. However, large oscillations will occur. So it is recommended not to set the voltage higher than the input one.

Output voltage oscillogram. VIN is 5V. VOUT is set above 5V.

Output voltage selection

Turning the potentiometer clockwise will increase the output voltage.

Efficiency and output current

Efficiency is defined as the ratio of output power to input power (Power out)/(Power in). This is a very important parameter in the case of operation with portable power sources (batteries and accumulators), where the time of operation on one charging cycle counts. The efficiency dependence on the input voltage is shown in the graphs below.

Dangerous voltage pulses

When connecting the power supply to the module, dangerous, short, high amplitude eclectic pulses (so-called pins) may appear, which may permanently damage the system. Polol's tests show that for voltages above 20V, the pins may have an amplitude exceeding 42V. In order to protect against this undesirable phenomenon it is recommended to solder a capacitor of at least 33 uF as close as possible to the pins supplying the converter.
