Hi Jeffrey,
Below comment for the tps2549 SCH:
1) The R111 and R112 value suggest choose 20K to set the current limit threshold at 2.7A.
2) The CS pin connect to the LM73606 feedback divider is not correct. The detailed parameter and connect method…

Hello,
i am designing a TEC controller based on dc-dc converters, similarly to what is reported in TIDA-050017. I would like to ask for some info about…
Hi David,
May I know the reason why Rboot affect the operating of LM73605?
All the test results are under no-load condition, usually, the recommended range for Rboot is 0ohm-10ohm. However, abnormal waveforms are captured when Rboot is more than 4…
Hello
You have listed several good points in your list; all of these should be carefully tested.
I think the the LM76005 would be a good choice, as would the LM73605 and LM73606.
We also have a newer device, the LM61460.
All of these devices use…
Hi,
I think the IC does not have the Forced PWM mode in this case where you can program the frequency to be fixed at all load condition. You have to add an unnecessary load to be operating in CCM mode
I would suggest, using the LM73605 or LM73606…
Hi,
Unfortunately this part would not be able to be paralleled for current sharing. You can try LM73605 or LM73606 for a higher output current buck converter.
Thanks

Hi Martin,
we don't have pin2pin or similar package part. The few available options are: TPS565208, TPS56637, LM73606, LMS3655. Please check the datasheet to see whether they are fine. If not, you can add more output capacitor to TPS56628.
The LM76003 can provide 3.5A DC load current. The EMI performance is pretty good. Careful filter design and PCB layout are essential.
The LM73606 can provide up to 6A DC load current, but Vin max is 36V.
Both of these two parts will have Q grade released…

Hi,
I just quickly made a calculator to doublecheck the design. See below:
I went through the app note to confirm if the LM73606 is a good fit for this flybuck application, and confirmed that it should be okay to use.
The calculation calls for…
