Hello Haiwen,
Thanks for using the e2e forum. It is possible to use a boost controller like TPS40210 or LM5156 for this. A reference design is given here: https://www.ti.com/tool/PMP9624
There are already some questions on this design within the e2e forum…
Hi JH Shin,
please have a look at this reference design.
This will be a good starting point for your design:

Hi Punith,
in case you have not already entered another ticket:
you can use e.g. the TPS40210 or LM5155/LM5156 with the approach as shown in this reference design:

Other Parts Discussed in Thread: LM5575 , LM61440 , LMR16010 , LMR16020 Hi,
Our project needs to convert +18V -> +10V and -18V -> -5V, each 100mA current max, switching frequency > 400kHz, both branches synchronized to avoid interferences. Spread spectrum…
Part Number: TPS61170 Other Parts Discussed in Thread: PMP9624 , Hi
We are considering -17V output from -24V input.
Input : -24V
Output :-17V/100mA
PMP9624 seems to be good reference for our design.
I think minor change should be worked.
Is it possible…
Part Number: TPS40210 Other Parts Discussed in Thread: PMP9624 Hi
Our customer are going to consider the configuration of the negative output from the negative input. （Vin=-15V,Vo=-6.8V, Io=1.5A)
So, we found some reference design at TI site. At the one…
Hi Ottey,
The 3A output current is too high for TPS55340 as a inverted SEPIC regulator because the current limit of TPS55340 is 5A.
Here is another option: http://www.ti.com/tool/PMP9624
By configuring TPS55340 as a negative input buck regulator, it could…
Hello byliu,
You would need a boost converter for this. Here is one example with the TPS40210 boost controller.
