Other Parts Discussed in Thread: PMP40441, CSD17551Q3A
Hi. Can you please explain the purpose of additional 150 pF capacitors (C19 and C20) at the gates of low side MOSFETs? I don`t see anything about it in datasheet and related documents.. In another schematic (PMP40441) there are only one additional circuit at the gate of low side buck transistor and rc-snubbers. In first case it seems to slow down turn on/off MOSFETs (total gate charge in spec is 6nC plus additional gs capacitance),in second vice versa(total gate charge in spec is 3.9nC plus additional charge/discharge current pump). Thanks!
