TPS61023: Pass-through mode

Dice-K

Part Number: TPS61023

Hi support team,

I understand that Pass-through mode occurs when VIN > VOUT.

I use TPS61023 under the following condition.
・VIN = 3V
・VOUT setting = 4.8V

At this time, if 5V is applied to VOUT externally, will it enter Pass-through mode?

Hi Dice-K,

No, it will not enter passthrough. The description in datasheet is a little inaccurate.

Hi Nathan,
Thank you for your reply.

Does Satoshi's TPS61023 usage below enter Pass-through mode?

Hi Dice,

No, pass-through will happen when VIN>VOUT & VOUT>target VOUT.
