Part Number: TPS61022 Other Parts Discussed in Thread: TPS63802 , TPS61033
Tool/software:
Hi everyone. I had seen this TPS61022 booster for my project which I will show you below. I'm looking for a DC-DC Boost converter with integrated FETs to bring…
Hi Kruthi,
While the voltage and current rating of an LDO are important to consider, all LDOs still have a safe operating region determined by power dissipation and junction temperature. Power dissipation is determined by both output current and voltage…
Hello Demian,
I was able to find unpopulated EVAL board Altium projects DEM-OPA-SSOP-3A, DEM-OPA-SSOP-3B, DEM-OPA-SSOP-3E, but not DEM-OPA-SSOP-3C and DEM-OPA-SSOP-3D. All of them have the same package, but different pinouts. The closest one to C and…
Part Number: LM3445 Tool/software: Dear
After the input voltage is powered off, the pin voltage of LM3445 COFF will rise to more than 9V.

Hello Andrea,
Thank you for sharing your board images and information about your design. I have a couple points to address:
a) Running the trace under the device will not cause issues in your implementation, as there is no switching occurring in the…
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…
Hi Sankalp,
I would recommend 2 pcs TPS62932 to get Input Vin 15V, output 3.3V(1A) and 5V(0.5A). It is 3.8-30V input, 2-A, 200kHz to 2.2MHz, low-IQ synchronous buck converter in SOT-583 package.
Thanks and kindly let us know anything unclear.

Hello Prathmesh,
The closest alternative to REG104FA-5/500G3 is TL1963AKTTR, which is offered in TO-263 (KTT) package.
For REG103GA-3.3, the best alternative is TPS7A2633DRVR which is not on the same package, but similar specs. Another option is TLV76133DCYR…
Hi Art Kay
I am really appreciated that you provide such a detailed explaination and very easy-undestand answer and simulation. Also very appreciate your reminder about inductive load's kickback. Now I know how to analyse the phase margin by simulation…
If you give me one with the same noise characteristic in the same package and the same supply and output voltage range...
Edit:
And common mode range. I need to "follow" +-15V at +-16.5V supply voltage.
2k input series R would do with regard…
