Hi Guys, I'm designing a low-power isolated supply (3.3V, Max ~50mA) and am keen to steer clear of transformers as EMI is critical to the design and I've had some noise issues with my previous transformer-based design. I have been looking at using a ...
Hi together,the VCONN voltage at STEVAL-USBPD27S is generated with a LDO. https://www.st.com/content/st_com/en/products/evaluation-tools/solution-evaluation-tools/psu-and-converter-solution-eval-boards/steval-usbpd27s.html#overviewUSB power delivery ...
Well, as you can see in the datasheet and the application note for LED1642GW, It doesn't use pure SPI, since it doesn't use CS but it requires the Latch Enable (LE) signal.I'd actually like to write an application to manage multiple LED drivers but t...
I'm designing a insulated 45V 54W flyback power supply using L5991. Feedback is closed via TL431 and an optocoupler, as in figures 33 and 34 of datasheet. To compute the loop gain I need to know the impedance of COMP pin but I don't find it in datash...
Hi,I am use L9916 for alternator project. I want to do OTP programming. but I could not succeed. I found only one document for programming. There are some issues that are not fully explained in the document.Field monitor pin, understood as the pin ca...
Hi All !This is my first question here so please excuse me if I wrong.My trouble: I can't found sources code for STEVAL-DPSTPFC1 Totem-pole PFC board. https://my.st.com/content/my_st_com/en/products/evaluation-tools/solution-evaluation-tools/psu-and-...
Hi,We have to design programmable power supply as per below spec 1. Vin: 230VAC, 50Hz 2. Vout: 0-120VDC or 20-120VDC, 12A max (variable with external control voltage from 0 to 5V) 3. Temp: -20 to +55 C Please suggest us any part number, this is for G...
I don't know why ST don't include the transformer winding details into the STEVAL-VP12201F ??I even cannot find it on Wurth Elektronik site, these complications make it impossible for us to use it in our products.Is there any help from ST around here...
What is the possibility to feed the eSTEVAL-VP12201B from PFC with 385VDC?Do I still need to apply any filter at the DC input of the eSTEVAL-VP12201B when feeding it from PFC?In another word, I would like to feed it from a PFC with 385VDC without L1 ...
I use powerstep01's datasheet "7.19 Supply management and internal voltage regulators".datasheet says: "VSREG must be always less than VBOOT". May be not Vboot, but Vbus?Also "The device can be protected from this event by adding an external low drop...
