Issue with STWBC86-Based Project and STEVAL-WBC86TX Evaluation Board
Hello everyone,I'm reaching out to the community because I'm encountering an issue with a Wireless Charger board we designed, based on STWBC86 and a similar architecture to the STEVAL-WBC86TX evaluation board.The main problem is the Power Transmitter...
Resolved! Reverse Recovery Time Trr of new FERD rectifiers family ?
From an ST newsletter I understood that ST is promoting new FERD diodes as "rectifiers for switching power supply". I could use these new diodes in a new flyback design so I downloaded a couple of datasheets and searched for Reverse Recovery Time Trr...
USB Device Not Recognized for STBC08PMR
Hello,On my custom designed PCB, there is a USB port for battery charging and programming ESP32 microcontroller. When I plug in to the PC, I get "USB Not recognized" message. In addition, the two LEDs are light up. In the datasheet of the charger IC ...

Wrong data while reading Current and capacity using STC3117 (STEVAL-ISB017V1)
I am using STEVAL-ISB017V1 (evaluation board of STC3117) with i.MX8MP board with linux. I am able to detect the IC and getting the data i.e. Voltage, temperature, current, and capacity. But the data for Current and capacity is not as expected. Curren...
Burning of resist. R154 of PM8834 auxiliary power to MOSFET driver of PFC of STDES-3KWTLCP ref dsgn
I have assembled PFC and LLC circuit of STDES-3KWTLCP reference design. I followed the procedure as described in the document to assemble whole circuit. When we gave AC voltage to PFC, resistance R154 gets heat up and eventually burn out. I double ch...
