Review on DROK 300001 Micro LED DC-DC Digital Boost Voltage Converter Adjustable Volt Regulator Board Module Power Supply Transformer by Payton Stovall

Well constructed boost converter that performs well over the specified input and output voltage range (assuming Vout > Vin). The built-in meter has an accuracy of ±100 mV. The switching frequency is in the range of 49-50 kHz; EMI is relatively low for open circuit (open) PS switching mode. Output voltage regulation is better than 2% for a nominal input voltage range of 5-30VDC and an output load of up to 2.5A. Overall, this is an excellent but cost-effective boost converter for general voltage conversion applications, including charging of medium-power photovoltaic arrays.
