Part Number: TPS65251

Hi expert,

My customer is wondering what is the maximum duty. Since we cannot see minimum on time and equation for maximum on time. Thanks a lot!!

Best regards,

Hi Ann,

It's just a limitation on maximum duty cycle decided by internal logic. Not related with minimum and maximum on time.
As maximum duty is 100% for this part, the HS can keep turning on until BOOT UVLO is triggered.

Sam
