TPS63900: VO(1) 3.4V

user4795239

Part Number: TPS63900

At TPS63900 can VO(1) be set to 3.4V (SEL LOW) ?
If so, what is the resistance value of RCFG3?

Hi,

I am afraid not, please set VSEL to high.

Thank you for answering.

What I want to do is to switch between VO2=2,8V (SEL High) or VO1=3.4V (SEL Low).

Hi,

Got, is it possible you can set VO1=2.8V and VO2=3.4V?

Is it possible to set VO(1) to +3.4V by changing the resistance value of RCFG3?
By the way, what is the current limit for VO(1)?

Hi,

I am afraid not, output voltage set by CFG is step by step but not linear.

current limit is still decided by CFG2. EX, when you set Vout by Vo(1) to 2.8V, then you can adjust current limit follow the screenshot below.
