Hi Bro,
My customer using BQ24600 for 5 batteries charging. The input voltage is 24V. When charging, we found the strange SW waveform when L is 10uH. After change the value of L1 to 2.2uH, some board's SW voltage waveform is PWM which seems OK. But some board is not. At first We think the problem is loop problem, but now we are confused and wish your answer. Many thanks.
