TPS63020: Need solution for output current 3A

Hi Sajna,

The TPS63020 cannot support 3 A under those conditions. The TPS63802 can, but thermally it might get a bit tight.

Is the 3-A output current continuous or in pulses?

Hi Milos,

Thank you for the prompt response.

3A is continous.

Datasheet of TPS63020 says it supports 4A of switching current. Hence it is supposed to support 3A of load current right? Correct me if i am wrong.

i have  also checked the datasheet of TPS63802, which says it will supports upto 2A.

can you please confirm?.

it would be helpful if you confirm me a part for my requirement

Hi Sajna,

It depends on the device how the switch current limit translates to the maximum output current. The TPS63802 is a newer device, with a higher switch current limit, lower switch Rds,on and better thermal properties than the TPS63020. The TPS63020 cannot support the continuous output current shown in its datasheet in Figure 1. The TPS63802 can support continuous output current shown in its datasheet in Figure 14. However note that this is measured on the TPS63802 EVM at room temperature and with the recommended layout. 

The TPS63806 can support a bit more current, but it comes in a BGA package.

hi Milos,

what would be maximum current TPS63020 would support for 5V output

Input is in the range 4.5V to 5.5V.

im in the middle of my design with TPS63020 for 2.7A output. Shall i proceed? or need to switch my design to TPS63806?
