Regulator Recommendation

Category: Hardware

Hello,

I need a regulator (buck boost?) that can handle an input voltage of at least 3-8.4V.  Currently, the input will be one LiPo cell (3.7V) but might become two in series (7.4V) in the future.  It is used to drive 3 BDC motors.  Generally, the motors can draw up to 2.5A together but I have seen short bursts >4A.  The output voltage should be able to be at least 6V.  Do you have any recommendations? (I came across the LTC3785EUF-1 myself.  Looks like something like that may work?)

Hello, The part looks good. You can also see LT3120/LT8392. My advice would be to use LTPowerCAD or refer to the datasheet to help you design your regulator and then simulate the design through LTSpice…

Hello, The part looks good. You can also see LT3120/LT8392. My advice would be to use LTPowerCAD or refer to the datasheet to help you design your regulator and then simulate the design through LTSpice to give you an idea how the design will respond. Regards, Jhun
