Posted on May 24, 2017 at 11:39Dear Sir/madam,There is available of ST92150JDV1QAuto development board int http://www.st.com. So, let me know is there any development board is available with controller.

Posted on March 25, 2017 at 19:28Hi:I have designed a smps using eDesignSuite with a VIPer38LE chip... the Power In is 11.1 watts, 96-144 Vac, 60hz and will run at 60KHZ.  Is there a method for determining the recommended filter components being X2 caps and the Common mode input choke?  Also the NTC?Thanks, Tom#common-mode-choke #ntc #x2 #emi-filter

Posted on May 09, 2017 at 14:59Hi,  Everyone!I'm Sorry about asking  PLC problem on STM32s MCU community.I have bought a PLC evaluation B'd that is STEVAL-IHP007V1 .And  make test enviroment like below.        PC <-- UART -->  STEVAL-IHP007V1  <---> AC Power LineI was installed  ST7580 GUI package on Window10 NotePC.The GUI connected to PC  via COM port.I tried to read status of  the STEVAL-IHP007V1  PLC module form GUI,But GUI  does not send any data to STEVAL-IHP007V1  PLC module.I was probe Tx line of COM port but  does not capture any siganls on the Scope.The GUI get Rx data from COM porWhat is problems on this.?Please help me,Thank  you#plc

Posted on April 12, 2017 at 05:06The ECM on my 1987 Ford Bronco has a TO-220 component labelled 'SGS 28710 5101FG'.  I cannot find any information on waht this is.  Is there a description or datasheet available?  I need to replace this component with a current equivalent.

Posted on April 06, 2017 at 17:13ST product selector doesn't have a selection for JTAG port.  What bi-directional ST Micro TVS would be optimal for a JTAG port to use for ESD protection?  Looking for a part number please.  ST improving the website to put JTAG in it's TVS selector list would be appropriate, (wishful thinking for ST's website).

Posted on April 04, 2017 at 12:46Hello,im quite new to the STM32 ecosystem and i'm looking for a board to start my IoT project.I found the SWPF01SA module but it is not clear if it is what i want (can't fine much on GPIO).I assume it doesn't have an ADC so i looked for a dev board. But which one?Regards,#spwf #wifi

Posted on March 31, 2017 at 14:45Hello Everyone.. I have come across ST710F microcontroller in one of our old designs. I tried to find the information about this microcontroller but I have not found any information. Is this part obsolete? If it is obsolete, then what is closest replacement for this microcontroller. Can anyone reply to this as soon as possible?

Posted on March 24, 2017 at 15:03Smart Transformer Selector and eDesignSuiteUsers of https://my.st.com/analogsimulator/ can now integrate Würth Elektronik Midcom’s transformers in their designs.Thanks to a partnership with Würth Electronik Midcom, we integrated their http://www.we-online.com/sts into eDesignSuite. Designers can start a project in record time, and more easily move to prototyping, thanks to eDesignSuite’s ability to generate a complete bill of material, and show the performance of the circuit under different operating conditions. http://blog.st.com/edesignsuite-

Posted on March 07, 2017 at 23:06HI:I've designed a SMPS with a viper controller, 3 outputs.  Is there a preferred way/tool to apply the design parameters to make an actual flyback transformer?  Magnetics has never been my strong area.Thanks!  Tom

Posted on March 13, 2017 at 14:32I've used the eDesignSuite to design a power supply using a VIPer38LE.  I'm verifying results and I'm having difficulty getting to the same primary inductance the design suite is.  Can someone get that info to me?  I am currently using the formulas in the Fairchild Application Note AN4137.Thank You!Tom

Posted on March 07, 2017 at 15:21HI:I'm using the eDesignSuite to design an AC/DC transformer that has a secondary at 135 vdc, 40 Iavg.  The listed turns ratio is 550.26m .... why the 'm' ?Here are the transformer details:Transformer Specifications: fsw: 60 kHz - Isat ≥ 982 mA - Lp: 1.62 mH ± 15 % - leakage ≤ 3 % Primary: Ipk 493 mA - Irms 201 mA - Iavg 123 mA Aux: Ipk 158 mA - Irms 16 mA - Iavg 3 mA - Prim/Aux turn ratio 5.64 Out 1: Ipk 198 mA - Irms 73 mA - Iavg 40 mA - Prim/Out 1 turn ratio 550.26 m Out 2: Ipk 5.93 A - Irms 1.99 A - Iavg 1 A - Prim/Out 2 turn ratio 19.79 Out 3: Ipk 581 mA - Irms 88 mA - Iavg 20 mA - Prim/Out 3 turn ratio 9.49Thanks!TomUpdate:  I see it now, just different than expected way for turns ratio.

Posted on February 25, 2017 at 23:11I am using ST's eDesign Suite for designing power supply. (AC-DC Converter)I contacted the transformer design firm to get my transformer designed.

Posted on February 24, 2017 at 20:50I'm looking at the STPTIC-82G2 ( barium strontium titanate (BST). The min operating frequency is >700MHz. Wonder if there's any similar part like the STPTIC-xxG2 with higher capacitance value and higher Q, Tuning ratio >7 for frequency of 100Mhz and above? Is there a manufacture where we can customize it?

Posted on November 27, 2016 at 04:27Hello,I am using the STEVAL-IME009V1, and I would like to modify the factory settings ''STSW-IME009_May_2014.dfu'' file to output the demo waveforms at 60kHz instead of 5MHz. Using the Dfu file manager, I extracted the DFU file to a hex file, but I cannot find where the frequency for the programmable waveforms is specified. Any help would be greatly appreciated.Thank you. #dfu #sthv800 #steval-im009v1
