AC?DC conversion system
Dear allI would like design a circuit for AC/DC conversion of a 3 phase AC voltage with different frequency and different amplitude. The input power of the circuit can be changed form 4W up to 300W. Actually, circuit input is generated by a output of...
STEVAL-PMIC1K1
Hi,Can I get the schematic of STEVAL-USBSTICK which is part of the set STEVAL-PMIC1K1 and acts as an USB-I2C interface, to get the details of the CN1 connector & the other pin details.
STWBC86 aplication
Hello,I am currently working on the implementation of the STWBC86 chip, following the STEVAL-WBC86TX as a guide. If we want to develop a PCB with the STWBC86 chip, is it possible to load the initial configuration by connecting the PCB via I2C with a ...
STPM801 - unknown pins?
Hello, We are evaluating the STEVAL-STPM801 board, testing the STPM801 as integrated hot swap, soft start and oring protections device. On the EVAL board the TM pins with nrs: 8, 13, 14, 27, 28, 29 are equipped with jumpers to select pull-up or pull-...
L7983PU50R
Hello,I am currently developing a device that uses the L7983PU50R as a 5V power source, based on the L7983PU50R - Evaluation board schematic.In the circuit, the 5V output is further used to power an LDO with a 3.3V output and a reference voltage sour...

Resolved! Clarification on Feedback Circuit of STEVAL-VP26K01B with VIPER26K
I am currently working with the STEVAL-VP26K01B evaluation board, which utilizes the VIPER26K IC, as part of an electric car project for Formula Student. During my study of the board's design, I noticed that the feedback is taken from a resistor divi...
Can't find STBC15QTR anywhere, it is out of production?
Just finished my design for wireless charging board with the STBC15QTR as charging controller. The chip marked as active production but i can't find the chip on estore.st.com, mouser or digikey. Where can i buy it?I could switch my design to STBC15LJ...
STUSB1600 can't work as source
Dear All, Hello everyone, I used STUSB1600 as the type-c dual role type power management. When it works as sink type, it is good. But when it works as source type, it doesn't work. I found VBUS_EN_SRC always keep high. This is my design schematic, co...
