TPS62220: EN/ UVLO/ Vin condition

Kurumi Hasegawa
Expert 7991 points
Part Number: TPS62220


Hi team,

 

TPS62220 has EN-pin and UVLO function. So when Vin>2.5V and EN=H, it will generate regulated output.

How does TPS62220 behave with below two conditions? Will the start-up sequence begin with soft-start? Or will it be undefined condition?

 

  • EN=H and 2.5V>Vin>[UVLO voltage]
  • EN=H and [UVLO directable voltage]>Vin

 

Best regards,

Kurumi

I am trying to contact the concerned team member who can answer your query. Please allow me some more time for this and I will update you as soon as possible.

    -> Understood, thank you for sharing the situation. The original deadline shown by the customer was Sept 16, so I applicate it if you could respond as soon as possible.

    -> Yes this query is coming from a customer. I cannot share details here (since it is public forum), but they are considering TPS62220 as other device's alternative.
