TPS61377: Devices with Pass-through mode

Part Number: TPS61377
Other Parts Discussed in Thread: LM5152-Q1

Hi support team,

I would like to boost the voltage of a 14.4V lithium-ion iron phosphate battery to 19V.
TPS61377 is a candidate, but it would be nice if it also had the Pass-through mode.
Are there any such devices?
Do you only have external FET devices like LM5152-Q1?

Regards,
Dice-K

    Hi Dice-K,

    Currently we've no boost converter with pass-through function.

    For boost controllers we have devices with pass-through function. Could you provided more detailed requirements, such as the Vin range, max Vout, Iout range, and any other needed function. With these information can we narrow down the device selection.

    If available, could you let me know the detailed application? And when will be in mass production?

    Regards

    Lei

    Hi Dice-K,

    Currently we've no available boost converters (integrated low side FET and/or high side FET) that has pass through function.

    I'll check with FAE on whether the information of unreleased device can be shared.

    For the boost controllers, we do have devices with pass through function. Such as devices LM5152 and LM5123. I suggest that you may open a new E2E thread with your detailed requirements and the target device LM5152 and LM5123. Then the E2E will be assigned to my colleague who responsible for boost controllers. So you may get better suggestions.

    Just let me know if you see any concerns.

    Regards

    Lei
