Helen,
Could I make a system like SLVA889 (Improving Boost Converter Reliability using TPS61178x Hiccup Mode Short Protection) using TPS61088 and the circuit proposed by PMP9779?
Dear Sir,
You need to add a disconnect MOSFET(or load switch) at the output side. You can refer to the TI design PMP9779 for a reference.
So you can also choose a TI part with load disconnect function, like TPS61022.
Dear Sir,
As TPS55340 doesn't has short circuit function, so extra component must be added. Please refer to the TI design PMP9779. The concept will be similar.
Part Number: PMP4451 Other Parts Discussed in Thread: PMP9779 Tool/software: Code Composer Studio Dear Sir,
Can I put a short circuit such as PMP9779 circuit?
How do I download the source code?
This specialty is provided at High School.
Ihope…
Dear Sir,
Since the TPS61088 upper side MOSFET has a body diode, so even EN is low, the Vout can't be zero, it is around Vout=Vin-Vf, where Vf is the voltage drop across the body diode.
You can add a MOSFET at the output side to disconnect the load…
Hello Nadhem, thank you for joining the Forum.
The Boost can not support an output short.
The Buck can not support an input short.
As an example for the boost question, please see this design example.
This reference design delivers an output…
Hi Yusuke,
Please check the TI reference design PMP9779 and app note SLVA819.
If you think the circuit is too complex, short circuit proteciton is not needed and you just need input output disconnect before startup, then I can recommend to you another…
