9 V / 3.5 A step-up converter outputs.
Leads of the step-up converter module
The module has four leads in the form of six holes for soldering connectors with a raster of 2.54 mm.
- EN - pin which switches off the circuit when the voltage is below 0.4 V, the circuit is switched on by default: 30 kΩ resistor pulled up from EN to VIN.
- VIN - input voltage from 2.7 V to 9 V (after starting up the chip, the input voltage may be at least 1.3 V).
- GND - system ground (common for VIN and VOUT).
- VOUT - output voltage of 9 V.
Hazardous voltage pulses
While connecting the power supply to the module, dangerous, short eclectic impulses with large amplitude (so-called pins) may appear, which can permanently damage the system. Pololu tests show that for input voltages above 11 V pins can have amplitude large enough to damage the module. To protect against this undesirable phenomenon it is recommended to solder a capacitor of at least 33 uF as close as possible to the pins supplying the converter.
System efficiency
Efficiency is defined as the ratio of output power to input power (power out)/(power in). This is a very important parameter when working with portable power sources. (Batteries and rechargeable batteries), where the working time on a single charge cycle matters. The efficiency of this circuit is between 90% and 95%. The output current depends on the input voltage and the system load.
