Part Number: TPS563210A
Other Parts Discussed in Thread: TPS563212, TPS563211

Hi,

I check the datasheet that the device can support input voltage range is 4.5~17V.

My customer design requirement is input voltage 4.7V and output voltage 3.3V, inductor is 3.3uH and max load is 1A.

Could you please advise whether the device can support the design?

Hi Jim,

TPS563210A cannot support this case because of max duty limitation .

I would promote TPS563211 and TPS563212, the next gen of TPS563210A, which can support your application with more good feature and better performance.

Below webench report file for your reference.

TPS563212 : 18V 3A ,1.2MHz

Hi Young,

Thanks for your suggestion.

May I know what is the max duty for TPS563210A ? is that limited by max ON time? I can find related information in datasheet.
