• RE: LM2677: Is input reverse polarity protection required?

  

  Orlando Murray

  Hi Craig, Yes you must have input reverse polarity protection on the LM2677. The highside MOSFET has a parasitic diode from SW output to VIN. This is reverse bias for positive VIN but if VIN is negative then you have two diodes (from GND) that will…

• RE: LM2677 in Parallel

  

  Juan Paulo Fung

  Resolved

  Hi Rikil, The LM2677 architecture does not allow for current-sharing and paralleling of multiple outputs since both control loops will be fighting each other. If you need wide-input voltage ranges similar to the ones offered by the LM2677 and currents…
