Hi,
I'm disty in Japan.
My customer is designing a prototype including the LMR14030 now.
He'd like to change the fsw frequency by S/W, so he is considering a external circuit.
I attached his current circuit plans.
*Cf. attached file lmr14030_extclock.xlsx
I have two questions.
In both of the circuit plans,even if the control signal is low (the output of external
control block is Hi-z ),leak current will flow approximately several hundred nA.
Question1)
Does that leak current affect the fsw frequency?
If that leak current has an impact on the fsw frequency,
how much does it affect?
Question2)
Is there any problem about the circuit plan2?
Best regards.
