hi,

I use the TPS40090EVM-002.

I want to adjust to the 2-phase, but it's not work.

How do i setup the EVM?

like CS2, PWM4 or any pin should to be floating, vcc, gnd or resistance to gnd?

Any reference scheme to offer?

thx!!

Hi Juncheng,

For 2phase mode, connect PWM2 and PWM4 to BP5, connect CS2 and CS4 to CSCN.
You can refer to the 2phase application diagram on datasheet page2.

Thanks
Qian

hi Qian

Don't remove original components of 2 & 4 phase on the EVM?

Don't impact on the components keep on the board?

Hi Juncheng,

Sorry for the late reply.

It should be fine to keep the original components of phase 2 and 4 on board.

Thanks

Qian
