Part Number: TPS54527
Hi,
Customer is using below circuit, and find the conducted emission at 12V——ADP is not met. Do you have any suggestions?
Thank you!
Part Number: TPS54527 Dears,
The spec of TPS52527 shows that output voltage is 0.76-6V,but customer design Vin 12V&Vout 9V,then they found the inductor is burned,rated about 25%.Detalis pls find below information:
1. Vin12V,Vout 9V,this design is…
Part Number: TPS54527 Other Parts Discussed in Thread: TPS54528 , We found that the TPS54527DDAR chip consumes too much power, with 12V input and 3.3V output. Even with all 3.3V loads removed, the 12V input has a self-dissipation of 30mA. Remove this power…
Part Number: TPS54527 Hi team,
Do you have an efficiency curve more closer than the figure 7 in the datasheet (12Vin to 1.8, 2.5V, 3.3Vout) with the titled case in order to estimate junction temperature from case-top temperature?
Best regards,
Hideki …

Takahashi-san,
Yes I assume this scope shot is taken in persistence mode and you are observing the jitter inherent to the control scheme of TPS54527. So, it is normal to have frequency variation.
In general, the DCAP2 control scheme has off-time jitter…

Do we have bom 2 bom or pin 2 pin compatible solution of TPS54527?
It could be higher or lower Iout rating, but same current rating is better.
