Hi Nitish,
I can only find the dying gasp IC, TPS65250. TI has a discrete solution reference design for your reference. http://www.ti.com/tool/TIDA-00304
I will close this case.
Part Number: TPS25940 Other Parts Discussed in Thread: TIDA-00304 , TPS61170 , TPS54495 Dear Sir:
In its datasheet, you say that TPS25940 maximum operating voltage is 20V ---page 4 describes that VIN, OUT ..... absolute maximum voltage is 20V. But in your…
Great!
Now I have two points to discuss.
1. There is a document TIDA-00304- "Last Gasp" Hold Up Energy Storage Solution; This is same sort of application I am looking for. Document having device TPS25940A. This device also seems suitable. Both ICs are…
Not that I know of, even this reference design utilizes three separate ICs:

Maybe the members of the non-isolated DC/DC forum will know of a single buck IC that contains a similar feature:

Other Parts Discussed in Thread: TPS61170 , TIDA-00304 Hello,
We intend to use TPS61170 to step-up voltage in order to store energy in a bulk capacitor. This capacitor will be from 3300uF to 6800uF and output voltage will be from 20V to 38V, we have not…
Hello Kunal, thank you for posting to the forum.
5 Watts for 22 seconds is 108 Joules. That is a lot of energy.
The concept for super cap backup usually uses both buck and boost modes of power conversion.
PMP9766 is a good example of this process.
