Hi Boggarapu,
Most bucks can be converted to an inverting buck boost topology by following a couple steps. Please refer to the guides attached. Let me know if you have further issues.

Hi Simon,
I was double checking my test setup from yesterday and noticed that I was using the incorrect low-pass filter setting in the AP, I corrected it and got the following results:
I tried 2 different configurations with the same results, using…
Hi Orwell and welcome to E2E,
What type of diode are you using and what is the desired hold time? I recommend building a working circuit in TINA-TI before you spend the time and money to put it together on a PCB. Look at page 3 of the OPA615 datasheet…
Part Number: DDC112 I am designing an instrument based on the DDC112 as a student project.
The lower part of figure 29 in the datasheet shows the DVDD power supply derived from the AVDD supply with a < 10 ohm isolation resistor. I would be grateful if…
Hi,
Yes, you can use the OPA699 in a standard difference amplifier configuration to use differential inputs. It's hard to estimate the exact propagation delay and it will depend on if you are hitting the limiters or not, but I would expect in the range…
Part Number: OPA860 Other Parts Discussed in Thread: OPA615 , DEM-OTA-SO-1A Hi,
Attached is the sample&hold circuit with OPA860, but the result is not correct with TINA simulation, please give me some advice. Thank you very much.

Christian,
Here are the programming values for the 4 devices. I found an RXDET[0] bit which did not need to be set.
Device 0 ( EQ = 01, VOD = 05, DEM = 02)

Shrikant,
You are correct, the pinout for the SLOU055 board is meant for a pin-out similar to the OPA2836. The evaluation module for the OPA2889 requires the use of the DEM-OPA-MSOP-2B EVM. If you can work with 5V supplies then the OPA2836 can be used…
Hi Brian,
The LM34927 is rated for 600mA of DC output current. The inductor is generally chosen to provide a peak-to-peak ripple current of 30-50% of the rated full-load current. With the minimum current limit setting of 700mA (corresponding to peak…
