LMR14050: Placement position of TPS2595

Part Number: LMR14050
Other Parts Discussed in Thread: TPS2595,

Hi support team,

I would like to add TPS2595 to the output stage of LMR14050.
Is it possible to place the TPS2595 just behind the inductor (in front of the output capacitors)?

Vin: 8~32V
Vout: 6.2V
Iout: 2.6A

If you have any problems or concerns, please let me know. The loop becomes unstable, etc.

Regards,
Dice-K

    Hi Dice,

    It's not recommended for below:

    1. The Ron will impact loop response which may require additional compensation on feedback resistor

    2. Once the fuse switch turn-off at inductor current is not zero, the inductor will generate unlimited high spike voltage which may damage TPS2595
