TPS62816-Q1: TPS61816 input current with offset and pulse frequency is about 1kHz

Part Number: TPS62816-Q1

Use the current probe to monitor Vin input current, there is DC offset and pulse(chip switching frequency is 2.23MHz). Is it reasonable for offset here,? And current pulse frequency is about 1kHz, is it reasonable? Or is there some problem for TPS62816 itself? Thanks for support!

        不合理,建议你先用芯片网站的webench确认一下电路,其次用电子负载确认一下是否是负载引起的。 上述如果都没有问题, 可以更换电感看看?
