Other Parts Discussed in Thread: LM5158
Tool/software:
I am using the LM5157EVM SEPIC converter. I am using LM5158 IC in the EVAL board. I am using a 24 V output and around 120 mA load. I have changed the feedback resistor R9 to 2.2k and R14 to 50k ohm. I have used 220uH 120 uH and 68 uH coupled inductors.
I am seeing a voltage drop as I am using a higher inductor at around 40 -50 mA and around 150 mA for 68uH. can anyone explain this drop to me and which inductor to use for better load regulation?
