TPS23754: Searching p2p compatible solution with TPS23754

Part Number: TPS23754
Other Parts Discussed in Thread: TPS23756

Hi team,

My customer is looking for second source solution for TPS23754.

I have discussed with customer about TPS23756.

The only difference is the TPS23754 device has a 15-V converter start-up while the TPS23756 device has a 9-V converter startup.

Therefore, customer would like to confirm whether they will need to change the transformer circuit and surrounding circuit of TPS23754 to feed the for TPS23756 feature.

Or do you have other recommended solution which can replace TPS23754 directly.

Thanks.

    Hi,

    Thank you for your question.

    TPS23756 is our only P2P for TPS23754.

    The TPS23756 has 9-V converter startup and so this device can support adapters from 12V to 60V.

    The TPS23754 has 15-V converter startup and this device can support adapters from 24V to 60V.

    If the customer would like to use the wider VIN range for adapters with the TPS23756, this will require a different transformer for wide VIN. But if the customer wants to use the same TPS23754 design and not change the adapter voltage, they can use the same transformer as in their TPS23754 design with the TPS23756. The Vc cap may also need to be increased to account for the lower converter startup.

    Let me know if this is not clear or you have any other questions about this. Thanks!

    Best Regards,

    Brett Colteaux
