TPS61169: TPS61169

Part Number: TPS61169

Hi Team,

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
