The controller increases the voltage in the range of 0.5 to 5.5 V to a constant value of 3.3 V. When exceeding 3.3 V on the input, the system automatically switches to the ropes regulator step-down voltage. The efficiency of the Converter is 70 - 90% depending on input voltage. To protect from overheating, the module will automatically power off if its temperature exceeds 140 °C. our range is also version with an output voltage of 5 Volts.
The module has three pins:
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 70 % - 90 %. The output current depends on input voltage, details on the chart:
Efficiency and output current IC with an output voltage of 3.3 V.
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 input voltages above 4.5 in heel may be the amplitude of a value high enough to damage the module. To protect against this undesirable phenomenon wlutowanie recommended capacitor value of at least 33 µf, as close as possible to the power pins of the Converter.
