Son Of Buck(SOB) is the next generation step-down converter.
Blanks NOT available. Only for Shoppe BK converter. Choose resistors and solder on value. Use the resistor calculator .
Choose resistor values and solder on value please.
Add desired output in the comments.
SOB Constant Current Buck Converter Board Uses all SMT components to step down and voltage regulate the output. Choose the resistor values of your choice. Use the BB/DB Resistor calculator. (p> Up to 85+% efficiency. Will operate with voltages ~3V-16V. The SOB has thermal protection. No reverse polaruty protection.
Will operate in DD mode when Vin is less than Vout (Vf). This board is compatible with the connectors and emitter board to make a sandwich module.
Caution: Please be aware that a 14.8V Li-Ion battery or battery pack when fully charged may measure 16.7V thus exceeding the 16V capacity of the SOB converter
