Other Parts Discussed in Thread: UCC21540, UCC5320
Hi team,
I would like to check with you if UCC23513 can support 120KHz, duty cycle = 1~2% application? I see UCC23513 has 105-ns (maximum) propagation delay.
with 120KHz, duty cycle = 2%, the SW ON time is between 1/120KHz * 1% = 83ns & 1/120KHz * 2% = 166ns, which is close to the max propagation delay of UCC23513. I am wondering if there has some issue.
If UCC23513 can't be used, perhaps we can suggest customer to use UCC21540(A), which has 40ns max propagation delay.
thanks.
Best regards,
Yang
