TPS53321: max duty of the device

Jim Tsai

Part Number: TPS53321

Hi,

I check datasheet and the device support input voltage range is 4.5~18V.

My customer design is output voltage=1.8V, the input voltage=4.5V is ok for the design, right?

The other question is the device has max duty cycle spec?

For example, if output voltage design is 5V, what is the min input voltage requirement?

Hello Jim,

Are you referring to TPS53321 here ?

For TPS53321, input voltage range is 2.9V to 6V.

Max duty cycle is given in the Electrical Characteristics Table depending on the operating mode.

Let me know if you have further questions.

Thanks a lot!
