NettetStep 2: Adjusting Output. This is a boost converter meaning that it will take lower voltage and convert it into higher voltage. To adjust the voltage we have to do a couple of steps. Connect the converter with the battery or other power source. Set the multimeter to read the voltage and connect the output of the converter to it. Nettet10. mai 2024 · ON Semiconductor’s LV52207NXB is a DC/DC boost converter for white LED units. It integrates a MOSFET that can tolerate 40 V. The resistance connected to terminal RT sets the maximum current. At 63.4 KΩ, the current is 20 mA. It is possible to set 256 steps of current values using the 1-wire control (Figure 5).
