The boost inductors (L102,L103) which u have redesigned is 15uH and the part number is 019890300R . But it is not updated in gerber. Can you please provide the data sheet of the old inductor( nductor, Toroid, Ferrite, 327 µH, 0.065 ohm, TH). The part number is 7840-09-0014.

Hi,
Can you please confirm the component U304 used in the circuit is LP2986AIMM-3.3/NOPB. The pitch mentioned in the gerber is 0.65mm which is for the SSOP Package ICs only. But no SSOP packages are available for LP2986 ICs .Only SIOC ,VSSOP and WSON are the available packages. Can we use VSSOP Package LP2986AIMM-3.3/NOPB as U304 for the same footprint.
Part Number: PMP20612
I build high-end tube guitar amps in one of which, currently I use a combination of three Mean Well power supplies to get 450V @ 500mA, 6.3V at around 2.5A and a 12V in the order of around 250mA. I am looking to move on from that because various aspects are non-ideal.
The PMP20612 schematic looks like it might be flexible enough, but I just do not have the knowledge or expertise to do this.
If someone could kick me in the right direction I'd be delighted.
I am thinking of getting a couple of pcbs fabricated (from the gerbers on the PMP20612 dev page) but need a wiser person than me to explain why that board will not work, if indeed it will not!
Many thanks in advance.

Dear Sir, I am trying to make this application more towards the hardware compatible. As I have to put manchester coding . I am trying to balance dc by sending a 1khz wave on the bus line. and if any data will be sent and change in dc line may detect the data. I have seen many modules which they majorly giving the hardware compatibility irrespective of the firmware. Can u help me in getting some better way for Dc balance?
Moreover i calculated the value for inductor and capacitor with my exact data signal rate. But it does not work fine.

For use in Altium designer simulation tool is there a PSpice model for this component or a way to use the HSpice model in the Altium designer simulation tool?
Part Number: TIDA-00449
Hello,
Is there any way to connect a Serial CAN BUS to TIDA-00449 Design which helps me in transferring data. Please attach few references which would be helpful.
Thanks.
Part Number: LM25145
Tool/software: WEBENCH® Design Tools
Hello,
I've been trying out the Webench Power Designer tool, however I'm not sure if a part of the generated schematic is correct.
It shows that the Vcc, PGood and SYNCIN pins should all be connected together and also to a capacitor to ground (circled in red below)
However I believe that only Vcc should be connected to the capacitor, PGOOD should be used as an output (or left disconnected), and SYNCIN depends on whether an external sync input is used or if diode emulation mode is used.
Is there a reason for this design, or is this a fault?
Thanks in advance,
Richard

Why the max frequency is now 50 kHz , before I could go much higher
Why do we use an 0R resistor in a series with an antenna trace while designing on chip antenna?

Hi
Power over RS485. Can I get the values of inductor which are been used for this application?
My data rate is 115200. will an exact schematic will work over RS485 on dc bus.
My application will be in an ideal condition much of the time, So dc saturation will be required so shall I go with trilevel with same inductance value.

Hi,
I am simulating a hysteresis comparator using LMV7219. It is working at 5V supply but not working at 3.3V supply. My circuit is using 3.3V supply.
Could you please let me know what is wrong with my simulation? Thanks, -Hongmei Wan

Tool/software: TINA-TI or Spice Models
Hi,
Can I set the input value over 3V?
In the following simulation, Vin is a triangle wave from 0 to 5V with DC level 2.5V. When it is 5V, the positive input (Vcs_o) of the op is 3.3V, what is the real output (Vcs_op)? the simulation value is 3.3.
Datasheet says the output will less 3V. I am wondering if I can set it over 3V for the input in real-life circuit? Does it get saturated when it is over 3V? Thanks, -Hongmei Wan

hello, In TIDA-00366 reference design, for isolated DC-bus voltage sensing AMC1311 is used, my question is that can i use AMC1311 for islolated AC voltage measurement ?
Part Number: TIDA-00570
Good morning,
We want to manufacture the TIDA-00570 test module, but we want to be sure that this will allow us to send at least 10000 patterns to at least 1Khz, otherwise, we would like to know that we should modify the design to achieve this.
thank you in advance.
Hello,
When we look for the devices from specification, it can be below image if some device selected. Is the below image able to export excel?

I am getting 'Irregular circuit' error message during a transient analysis. The schematic passes ERC checking.

Part Number: TIDA-00195
Dear sir,
In general we will use snubber capacitors for the IGBT protection while using inductive loads. But there is no snubber capacitor or any other snubber capacitor is used for the IGBT protection in TIDA-00195.
Could you please tell me, how the IGBT switch is protected against inductive loads for the inverter?
also we are planning to use FP75R12KT4. Do we required snubber protection for this IGBT.? Kindly confirm the same.
Thanks & regards,

Dear Champs,
I am asking this for our customers.
1) The user founds the system will get shut down if the AC input is about 115V and the output power is less than 100W. Is there something wrong on the user's side? OR is it same on your side? If it is same on your side, what is the reason? For example, the system has not dealt with light loads? unexpected trip?
2) Do we have any idea and/or suggestion about the control mechanism for PWM switching rate faster than 1.2MHz? OR do we have any plan for that?
