TPS55332-Q1: TPS55332-Q1 max duty cycle

Hi team,

My customer is looking for solution to do input 7.5v, output 45v.

The datasheet says the max duty SYNC is 70%.

in my opinion, we don't use the SYNC and I use the toffmin to calculate.

if we set lower frequency, we can get Dmax >84%.

Could you please help double check it?

Thanks.
