We are planning to use TPS61169 as a IR LED driver in our design. The requirement are as follows,
- Input voltage : 5V
- Output voltage : 18.6V
- Output Current : 100mA
In datasheet, Its shown that the inductor value is 4.7-10 uH. But in my calculation, for our requirement more that 22uf is need to minimize the ripple current below 40%.
So please let me know if i can follow the design with 10uH.
Please find the snapshot of my design below,
Please reply ASAP
