Hi Sir,
may we know about minimum on-time limit?
we condition as below:
Vin=30v,
Vout-3.3/1.5A , we choice is the B version(1.4Mhz) and DDA package.
but we calculated duty cycle is 0.11%, if use swutch frequency is 1.2Mhz~1.6Mhz , that the calculared minimum on-time is 91.6n/s~68.75n/s, if refer to the maximum value as below chart, have any risk?
