Other Parts Discussed in Thread: LMR33630, LMR33620, LMR33610
Hi
I used LMR33630AQRNXTQ1 in my project. There are some questions when choosing inductance.
When I simulated DC / DC using TI's WEBENCH : Input 9-16v(typical 12V), output 6V, 1.5A, and the recommended inductance of L1 is 8.2uH. When I change the output current to 0.6A, The L1 is also 8.2uH. This inductance seems to be independent of the output current.
But if I used the Equation 4 in datasheet(SNVSB26C – JUNE 2018 – REVISED OCTOBER 2020) page 21, calculated the inductance value is about 16.7uH.
If my input voltage is 12V, output 6V@0.6A, Can you help me to select which value of inductance?
Thanks.
Best regards.
