Part Number: LM5122 Other Parts Discussed in Thread: PMP10886 , PMP30491 , We are willing to implement a synchronous SEPIC with the LM5122 as described by the PMP10886 & PMP30491 reference designs. Would it be possible to implement the current sensing…
Hello Mike,
for the coupling capacitance typically ten times input capacitance and Miller capacitance of sync FET is sufficient; we don't care too much here, just taking 1uF that is good... If you look at my smaller PMP30491 you'll find 1uF there as…
Hello Terry, PMP30465 has been tweaked to high input voltage 80V by using pre regulator; you ask for 20V input only... Just have a look at my SEPIC PMP30491 using LM25122; this ctrl. is able to handle 3V input and by using synchronous rectification you…
