A 5V, 1A wall adaptor powers the system through a 2meter cable attached before C48. The output load is very light, typically less than 100mA.
At power-up with ILIM connected to 100K, the IN pin has a periodic glitch, about ever 1msec. This prevents our down-stream buck regulator from running.
If I reduce ILIM resistor to 35.6K, this glitch goes away and the system runs normally. Does anyone know what causes the circuit to not function when the ILIM is 100K?
Thank you
