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…
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…
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…
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.
