The controller increases the voltage in the range of 0.5 to 5.5 V adjustable with potentiometer values from 2 to 5.25 V. in excess of 5.25 V at the input, the system automatically switches to the ropes regulator, step-down voltage. The efficiency of the Converter is 70 - 90 %, depending on the input voltage. The system has a standby mode is activated by setting the state to low level output SHDN. In our offer we have also version with an output voltage of 5 V and 3.3 V.
The module has three pins:
Voltage is set using the potentiometer. Turning clockwise increases the voltage.
Fig. 1: Select output voltage.
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:
The efficiency of the system with an output voltage of 3.3 V.
The efficiency of the system with an output voltage of 5 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.
