Brightness W Indicator Step Down Power Supply Current Sensing Resistor
Output prevent backflow: None. Made from a dedicated for IC and high- for precision for current sensing resistor, proving a more stable constant for current, (when 20° to 100° constant for current 1A, temperature for drift less than 1%).
DC DC Voltage Converter Step Down/Up Regulator Voltage Reducer 8V-40V to 12V 3A
The conversion efficiency may reach 95%.
