How about STEVAL-SMARTAG1？
I have a project about using NFC to collect sensor information without power supply, but the current EH output energy cannot be directly connected to the nucleo voltage pin of STM32L476RG, so can I refer to the design of STEVAL-SMARTAG1, adopt the de...
M48T58Y-70PC1 timekeeper packaging
Hello, I need to replace a ST timekeeper model number M48T58Y-70PC1They are on an extended back order. They have another battery model number 511-M48T58Y-70MH1F available, however the packaging is different. Are there adaptors available where I wou...
PD3.1 adpater topology
Dear experts,I am looking for a solution for PD3.1 adpater. below are my questions.which topology is suitable for PD3.1 adapter, ACF or AHB Flyback? could you please explain why?why the power below 65W, the topology is usually use ACF rather than AHB...
How about SL-CNWLC05801V1？
At present, I have contacted the project about NFC power supply, but there has been no progress. The energy output through the EH pin of ST25DV has not successfully powered L4(MCU). Currently we know that SL-CNWLC05801V1 uses STM8, can its MCU be pow...
Suppress Inductive Energy when Triac Fired at any angle.
The above waveform attached shows input sinewave which is stepped down using transformer and I am using voltage based zero cross detection for firing Triac. Above waveform shows TRIAC is fired at almost 10% of Positive and Negative Half cycle. I w...
iso808 continuous current calculation
hello I have gone through the datasheet of ISO808. In the datasheet ILim is 0.7A but for Channel Output Current (continuous) it is mentioned as internally limited. could you please give data for that or Is there any formula to calculate per channel...
Resolved! Looking fro high speed LED driver
Hello,Not sure that the product I'm looking for exist. It should behave like LED driver but after looked through different LED I didn't find a product that meet my requirements:can drive 1 ... 15 LEDs connected in serieshave a possibility to change c...
LD1084 noise and spice recomendationss
Hello i want to use the LD1084 voltage regulator . I need to build a decoupling networks on the inputs and outputs of it. Is there are some recomendations regarding decoupling networks of this noise. Or if you have spice model of this component? Than...
Linear regulator ripple
We have a +/-12V regulated power supply as part of our board design.The board takes a 5V input and passes this though a TI DCP020515DU DCDC. This gives us +/-15V unregulated. Each 15V rail has been tested with loads up to 60mA (our requirement is 30m...
[STUSB4500] Not able to get output in PDO2 with 3 PDOs enabled
Hi,I am facing a strange problem regarding the PDO2 output in STUSB4500. Inspite of setting PDO Number as 3 and configuring the PDO2 voltage and current values using the STSW-STUSB002 GUI, I am not able to get any voltage output at PDO2. The status L...
