R154 of PM8834 auxiliary control to MOSFET driver of PFC of STDES-3KWTLCP reference design? (Burning of resist)
Hello, Well, if R154 gets as well hot, there will clearly be as well much current streaming through it. If you don't mind check C161 and its cover. At that point moreover check the signals on PWM1, PWM2 and OUT1, OUT2 on U105. Regards

Hello,
Microcontrollers play a vital role in optimizing power consumption to extend battery life in battery-powered devices. Here are some common techniques used by microcontrollers to achieve power optimization:
It’s important to note that the specific power optimization techniques available and their effectiveness can vary depending on the microcontroller’s architecture and features. Hope this is helpful for you.

See lessHow to reset factory chip STWLC38 without I2C link?
Hi.We as it were utilize I2C to upgrade fw, it would be ideal if you make sure FT260 dongle is ok , about GUI connect issues, i propose you use a1_wlc38_downfw.bat to download fw automatic. Also it would be ideal if you check GUI log and post it if still fail. Thank You

How to Interrupting both Cores on ESP32 S3?
Hi, Do not pin your task to a core. When an unpinned task becomes runnable, it'll be planned to whichever center is available at that moment. That's not going to happen. 10-15us is the normal time it takes to switch contexts, e.g. from ISR to a task's context; there's nothing you may do around thatRead more
Hi,
See lessDo not pin your task to a core. When an unpinned task becomes runnable, it’ll be planned to whichever center is available at that moment.
That’s not going to happen. 10-15us is the normal time it takes to switch contexts, e.g. from ISR to a task’s context; there’s nothing you may do around that you can do a few things inside the ISR itself, which saves the 10us for the setting switch, but indeed an ISR can have delay/jitter within the order of a microsecond or more.

Hello,
An IoT (Internet of Things) toolkit is a collection of software development tools and resources that help developers build and deploy IoT applications and solutions. These toolkits typically provide libraries, APIs, and frameworks that simplify the process of connecting and managing IoT devices, collecting and analyzing data, and building applications on top of IoT platforms.
To use an IoT toolkit, you typically follow these steps:
It’s important to note that each IoT toolkit has its own specific documentation and resources that provide detailed instructions on how to use them effectively.

Hello,
How do you choose the IGBT category according to current and voltage?
Hello, You choose an IGBT with abs maximum voltage of about 20 advanced than the expected collector-emitter voltage at the worst condition (you count your topology, switching voltage spikes, inputover-voltage). You choose the IGBT current rate according to Tj and power dispersion. Abs maximum currenRead more
Hello,
You choose an IGBT with abs maximum voltage of about 20 advanced than the expected collector-emitter voltage at the worst condition (you count your topology, switching voltage spikes, inputover-voltage). You choose the IGBT current rate according to Tj and power dispersion. Abs maximum current drops at advanced temperatures. So choose proper cooling, it might be you need to parallel devices to achieve advanced current. You also have to consider peak current so that it would survive.
Keep in mind there are numerous other parameters you have to consider, for example, dynamic characteristics, ability to operate at short circuits (10us specified generally), and so on.

Hello,
I did this numerous years ago, so I’m still determining what has been modified in the software. But back also you could configure to use GPIO0 as the CLK.
The problem with this was that it didn’t allow uploading the firmware automatically. You had to manually keep GPIO0 low and reset it to put it in bootloader mode for downloading. I wouldn’t say I liked this approach so I did it this way rather.
I do not use that design presently, mostly because I only use the ESP32- S3, and there’s no stock of the LAN8720A. When I need Ethernet I use the KSZ8851SNL Ethernet Controller. Works great.
