Other Parts Discussed in Thread: TPS55340, LM5122, PMLKBOOSTEVM

Hi, I bought a PMLKBOOSTEVM with that contains TPS55340 & LM5122, but I don't know how can I define the output voltage according I want, that is 18 V. How can I do that?

Hi Lucas,

Thank you for your interest in our product.

This EVM is just an expansion that integrates the two EVMs. Please specify which controller IC you would like to use? TPS55340 or LM5122?

Thanks,

Yinsong

Hi, I had a problem with my account to post questions. I want to use the LM5122, because I need a control external of PWM

Hi Lucas,

If you just want to modify the output voltage, you can change the feedback resistors. Since 24V to 18V is not too big of a change, the compensation should be fine. But if you see unstable operation, you will need to adjust the COMP and slope.

Thanks,

Yinsong
