Product description: U3V16F3 - step-up converter - 3.3 V 2 A - Pololu 4940
Pololu step-up converter with an output voltage of 3.3 V and an efficiency of 2 A. The supply voltage is from 1.3 V. The minimum voltage required for start-up is 2.7 V. Typical converter efficiency is from 85% to 95% , depending on the input voltage and load. The output current is proportional to the input current, efficiency and the VOUT to VIN amplification factor. The input voltage (VIN) should not be greater than the output voltage (VOUT).

U3V16F3 converter pinouts
- VOUT - output voltage 3.3 V
- GND - system ground (common for VIN and VOUT)
- VIN - input voltage from 2.7 V (after starting the system, the input voltage may drop to min. 1.3 V)
Voltage spikes
When connecting the power supply to the module, the initial current supply can cause dangerous voltage spikes that are significantly higher than the input voltage. After research conducted by Pololu, it was found that for input voltages above 9 V, the pulses can have an amplitude large enough to damage the module. To protect against this undesirable phenomenon, it is recommended to solder a capacitor of at least 33uF as close as possible to the converter power pins.
Converter system efficiency
Efficiency is defined as the ratio of output power to input power (Power out)/(Power in). It is one of the most important parameters of the converter, especially when working with portable energy sources.
