Dual 12V Step-Up Voltage Regulator (U3V70F12) setup

Hello, I have two 12-V step up regulators from Pololu (U3V70F12).

I was wondering if it’s possible to use two of these in parallel with a diode on the VOUT pins to effectively double the output current. I was wondering if both regulators would then share the load and be more efficient at lower voltages or would this setup cause some issues?

My goal is to increase the efficiency of the setup to provide more power as increase the voltage input isn’t an option in my case.


In general, we do not recommend connecting regulators in parallel since it is difficult to ensure their voltages match and that the load is distributed evenly across them. You might this thread helpful.

Thanks Jeremy. I suspected as much, but some boards can be parallelized since their ICs support it. I just wasn’t sure if this one could.
