Part Number: OPA353 Other Parts Discussed in Thread: TIDM-DC-DC-BUCK , , TLV2621 , OPA365 I am designing a DCDC 40V-100V converter with digital control very similar to TIDM-DC-DC-BUCK( https://www.ti.com/tool/TIDM-DC-DC-BUCK ). I need some help choose/design…
Part Number: OPA353
I read the Operational Amplifier Stability Document that is written by Tim Green.
When I note ROUT= RO/ (1+Aolβ). Then Tim Green gives an example with OPA353.
Please check the attach.
In the formula, 1/β= the closed…
It looks like you are using the SNAA287 application report for the filter design. The AC TINA response looks like the passband is in the 500kHz range. Note, I was unable to find a TINA model for the LMV881 as suggested in the application note…
Where Can I find an explanation for the software?
The buck_nonpowerSUITE project is for F28004X. What all the changes needed to port it to F28379D?
Instead of U2-OPA353 for current sensing, Can I directly use some current sense amplifiers? like INA293…
Part Number: BOOSTXL-BUCKCONV Other Parts Discussed in Thread: OPA353
Refering to the schematic of the DPS Booster Pack:
Why is the output of U2 (OPA353) tied up to Vdd 3.3V via a 10K resistor?
This is a differntial amplifier for the current sense resistor…
I tried to use OPA353 for the same application. Here input is 1.6V.I used the compensation capacitor calculated by using the equation given
in the datasheet but the output is still oscillating. May I know why.
Part Number: BOOSTXL-BUCKCONV Other Parts Discussed in Thread: OPA353 I have this BOOSTXL-BUCKCONV with Lanchpad F28379D as my setup.
HW setup: - 200KHz PWM frequency - ILFB (Inductor current feedback, unfiltered) pin for sensing current - : H2 - V…
Other Parts Discussed in Thread: OPA353 Hello together,
is there the possibility, that someone loads up again the Burr-Brown application note zip files, because the original thread is not available anymore.
I would like to thank you in advance.
Kai's points are good - you may consider using a higher bandwidth device and see if the results improve. With more bandwidth, you'll have better performance at 300kHz.
A device like the OPA353 or something from our high speed product family:…
