Hi,
My customer find the EN pin drop waveform at power up.
Could you please let me know the reason of this behavior.
It is occurred before Iout rising timing and Switching start timing. They cannot find Vin drop.
Does TPS62823 EN pin have around 4uA sink current at internal circuit power up? (0.4V drop = 100kohm(Vin to EN) x 4uA)
Vin and EN, same timing power up (pulled up with 100kohm )
Ch1:Vin
Ch2:EN
Ch3:SW
Ch4:Iout
Vin power up >> Then, EN ON
Ch1:Vin
Ch2:EN
Ch3:SW
Ch4:Iout
Thanks
Muk
