• LM5171: Is IMON 'bidirectional', similar to ISET, when in Boost FPWM mode?

  

  Dan Quixoté

  Resolved

  Part Number: LM5171 Tool/software: When ISET goes below its 1V offset when LM5171 is in Boost/FPWM mode, which makes buck operation happen as shown in datasheet Figure 7-28 (and on the front page), does IMON also go below its 50uA offset to indicate reverse…
