Hello team,
I am considering 24Vin, 5Vout, 3.2A with TPS56637 and I have questions.
- TPS56637 datasheet table 4 shows recommended component values.
I think the recommended values are for stability purpose to keep LC double pole location within optimal range.
Can we use different inductor value from the table recommendation if we keep L x C range?
For example 5Vout case, datasheet recommends 3.3uH and 20uF(min) to 100uF(max) as output LC.
Can we use 10uH and 20uF which is within L x C range for 5Vout with lower ripple current? - In case calculated peak current is about 3.6A, is an inductor with 5.8A current rating good choice? or should we use an inductor that support higher rating than current limit(8.6A max)?
Best regards,
