Leads of the step-up converter module
The Pololu step-up voltage regulator module is equipped with four outputs in the form of six holes, to which you can solder the included connectors with a pitch of 2.54 mm.
- EN - pin that turns off the system after applying voltage below 0.4 V, the system is on by default: a 30 kΩ resistor pulled from EN to VIN.
- VIN - input voltage from 2.7 V to 12 V (after starting the system, the input voltage can be at least 1.3 V).
- GND - system ground (common for VIN and VOUT).
- VOUT - 12 V output voltage.
Dangerous voltage pulses
While applying the supply voltage to the module, dangerous, short electric pulses of large amplitude (so-called pins) may appear, which may permanently damage the system. The Pololu company has carried out tests which show that for the input voltage above 11 V the pins may have an amplitude large enough to damage the module. In order to protect against this undesirable phenomenon, it is recommended to solder a capacitor with a value of at least 33 uF as close as possible to the power pins of the converter.
System efficiency
Efficiency is defined as the ratio of the output power to the input power (power out) / (power in). This is a very important parameter when working with portable energy sources. (batteries and accumulators), where the working time per one charging cycle is counted. The efficiency of this system ranges from 90% to 95%. The output current depends on the input voltage and the system load.

Specification of the step-up converter U3V40F12
- Input voltage: 1.3 V to 12 V (the minimum voltage to run the system is 2.7 V)
- Output voltage: 12 V (with 4% accuracy)
- Typical efficiency: 90% to 95% depending on input voltage and load
- Switching frequency: ~ 600 Hz under heavy load
- Energy saving mode
- Typical idle current less than 2 mA without load
- The 9.5 A switch allows you to:
- instantaneous input current up to 9.5 A
- input current up to 4 A for a few seconds
- input current up to 3.5 A for an extended period of time
- Integrated security:
- too high temperature shutdown
- the soft-start function limits the inrush current and gradually increases the output voltage
- output overvoltage protection (typically 16.5V)
- input current limitation cycle-by-cycle to 9.5 A
- Dimensions: 15.2 x 15.2 x 5.6 mm
- Weight: 1.5 g
