Part Number: TPS40170EVM-578 Other Parts Discussed in Thread: TPS40170EVM-597 Hi sir,
May I have your help to check the differences between TPS40170EVM-578 and TPS40170EVM-597?
Which one should be suggest to apply if customer wants to evaluate EVM?
Thank…
Part Number: TPS40170EVM-578 Other Parts Discussed in Thread: TPS40170 , Hello,
We would use the TPS40170 to ahieve 24V/10A output, 48V input, which used in the product of broadcast monitor controller.
We have the TPS40170EVM-578 but also want the design…
Hi Piotr,
thank you for your reply. As I posted initially, I use the TPS40170EVM-578 so all pcb layout will be found there. The coil is shielded Coilcraft XAL1010-153MED.
Thank you for the app note. I did not see that before.

I made a buck with TPS40170.
input voltage specification is from 22 V to 25 V and output 12 V 4~6 A.
it almost same of TI EV BOARD TPS40170EVM-578 . But I first made 2 layer small…
Short conclusions after more in circuit testing:
TPS40170 is a fine and versatile IC for voltage mode control of a synchronous buck converter.
However my main fault at designing the circuit was the high ringing at the switch node. All scope shots below…
