Other Parts Discussed in Thread: LM5163
Tool/software:
Hi team,
My customer use LM5168 with VIN 30V, VOUT 13.3V, when they increase current load from 0A to 10mA(electronic load CC mode), the VOUT will collapse to very low voltage about 3V-4V.
I test output voltage and current ripple, seem to be abnormally larger. So I add 100pF Cff, then it can work well. Not sure if there is something wrong with the circuit, such as loop stability?
I found datasheet show we can use lowest cost circuit without any Cff or RC
Pls help comment that. Below is schematic, note: customer actually use LM5168FDDAR, not LM5163
