Hi,
I am wondering if there is any information you can share on the leakage current into the enable pin? Specifically when LOW but any information would be helpful.
Thanks!
Reed

Hi ReedKacz:
Sorry that the expert for TPS61022 is out of office these days, the reply will be delay.
May I know the what's the purpose that you care about the leakage current of EN pin especially LOW?
Minqiu,
The question is along the lines of learning how large of a pull-down resistor can be used on the enable pin. If we used >1Mohm and the leakage is large then there may be false enabling.
Thank you,
Reed
Hi Reed:
If use too large resistance, the noise may make converter misbehave. It's better to connect to GND directly without resistance.
If the pull-down resistor is necessary, please share more details about the control principle.
Hi Reed,
Thanks for reaching out for TPS61022.
It'll take some time to get the enable pin leakage pin information from designer team since they're having Chinese new year holidays. Generally, the leakage current is really small, a 1Mohm pull down resistor for enable pin should be ok.
