Dears,
As below circuit, my customer found when VCC power on quickly(like about <3ms), the TPS61040 cannot startup. If slower down the VCC power up, the TPS61040 become normal. So what is reason for that and how to solve the issue? Thanks.

Hi Jing Ji,
It has no issue to test without load. But customer's load is actual LCD screen. So could you please add some capacitance to simulate the load? like several uF to hundreds of uF?
Hi Jing Ji,
What's your email? I can send you customer test waveforms. and we can discuss more offline. Thanks.
