Description of product: Pololu boost Converter adjustable in 2.5-9.5 V 2A

The regulator increases the input voltage range from 1.5 V to 9.5 V on the output, adjustable with a potentiometer from 2.5 V to 9.5 V, under the condition that the output voltage cannot be higher than the input. Continuous current up to 2 A allows the power electronics and actuators, e.g. DC motors. In our offer we also have a system of this series with output voltage of 4 V to 25 V.


Examples of usage

  1. Chip logic that requires a voltage supply of 3.3 V or 5 V small, low voltage battery.
  2. The power of sensors, systems that require 5 V in systems that supply 3.3 V
  3. The power of a large number of LEDs

The output of the Converter

The module has three pins:

  • VIN - input voltage
  • GND - the ground
  • VOUT- output voltage


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 with wires.

The choice of the output voltage

Voltage is set using the potentiometer. Turning clockwise increases the voltage.

The efficiency of the Converter depends on input voltage and output voltage. The average is from 80 % to 90 %. The maximum current which can provide the layout, 2 A.

Fig. 3: the efficiency of the system with output voltage of 12V.

Jumping voltages (pins)

In electronic circuits, the current run can lead to the emergence of so-called pins, that is, sharp voltage spike to a value above a certain level. If the amplitude of the pin exceeds the permissible value of the controller, it can fail. Therefore, if the system will be powered with voltage above 10V or load will have a high inductance, we highly recommend you wlutowanie capacitor value of 33uF/25V or higher, as close as possible to the system between VIN and GND.
