LM63625-Q1: EN and VIN timing

Yuya Shoji

Part Number: LM63625-Q1

Hi team,

I have a question.

If the EN is high before VIN goes high, can this device properly wake up?

Best Regards,

Hi Shoji-san,

The VCC LDO won't turn on and device can't function without VIN being high.

Thanks,

Andrew

Hi Andrew,

So, my diagram is correct, right?

Hi Shoji-san,

The device can properly wake up when VIN goes back up. Your diagram is almost correct.

I think the only thing is that VOUT ramps up high rather than going straight to VOUT.

Thanks,
Andrew
