Hi
This is the right way. This is not a complicated design.
I think you can start with LM5156EVM https://www.ti.com.cn/tool/cn/LM5156EVM-BST . The EVM has similar
And you may also refer to below application note and design calculator.

Part Number: LM5156H Other Parts Discussed in Thread: LM5156EVM-BST Hi Team,
I have a question about Demoboard LM5156EVM-BST.
now, I try to change the voltage IC with Demoboard LM5156EVM-BST,
testing condition is
>Input voltage 12V,
>Output voltage…
Part Number: UCC14240-Q1 Other Parts Discussed in Thread: LM5156 , LM5156EVM-BST Hi Experts,
I am trying to power the UCC14240 from the LM5156.
I am evaluating with the LM5156EVM-BST, but the output ripple voltage is the worst condition of 29.5V( <50ns…
Hi Sekar,
I see but the values of the RC filter seems to be too small, could you change the R7 to 800 to 1k ohm?
As for EVMs we only have this LM5156 Boost https://www.ti.com/tool/LM5156EVM-BST and also there is this LM5156 Flyback reference design https…
Part Number: LM5156-Q1 Other Parts Discussed in Thread: LM5156EVM-BST , LM5155 , LM5156 I need a design using LM5156 in boost CCM or DCM mode for input voltage of 12V to 24V and an output voltage variable between 50V to 200V and a current of 5ma max at 200V…
Hi Marvin,
Let me clarify my previous message. The LM5157-Q1 Boost EVM has the same configuration as the other two mentioned by you (Input voltage range: 3 V to 9 V) and in addition the IC itself has a lower voltage rating. To use the LM5158EVM-BST or the…
Hello,
Thanks for reaching out. Unfortunately it is not allowed to short the CS pin to ground as this device is operating in peak current mode control and therefore sensing the current is fundamentally important. The compensation components cannot be…
Hello,
Thanks for reaching out. VBIAS is intended as the input voltage to the IC: The VCC pin is the output of the internal LDO (as you can see at page 12 of the datasheet). The output of the VCC pin is 7V when it is not in dropout. In this figure you…
Hello Marcin,
Thanks for the update, I will stay tuned for further developments. You are right about the layout, the FB divider is a sensitive component and should be placed as close as possible to the IC, connected after the Cout (to avoid the noise…
