STEVAL STWBC86TX programming
Hello, I would like to program a board with the initial configuration of the STEVAL STWBC86TX. To do this, I need two files: PATCH and CONFIG. Where can I download these files to the STSW-WPSTUDIO GUI of the test board we have?
Looking for STWBC2-HP Fixed Power Output Firmware
大家好，我目前正在研究基于 STWBC50-HP 芯片的 2W 无线功率发射器。我的目标是在不使用 Qi 协议的情况下验证硬件功能，用于学习和测试目的。我已经完成了发射器硬件设计，现在正在努力寻找一种无需 Qi 通信即可输出固定功率的固件，例如演示或示例项目，例如：STWBC2-FW-固定功率输出、或任何允许恒定功率输出（例如，19V 2.6A）而无需协议协商的类似固件。不幸的是，我在 ST 网站资源或 STM32Cube 软件包中找不到确切的固件。任何人都可以分享下载链接或提供在哪里找到此固件...
ST L4986A not working
We’re currently facing an issue with the L4986A PFC controller in one of our designs. The IC is not functioning as expected, and we would appreciate your guidance.:wrench: Issue Summary:• The IC receives all input voltages within the recommended oper...
TCPP03 compatibility with FETs that have a low Vgs(min)
We are looking at using the TCPP03 and TCPP01 for a system with a dual-role power port and a sink port. We want to use this dual MOSFET with both ICs (a dual MOSFET is needed for the TCPP01 to prevent backflow): https://fscdn.rohm.com/en/products/dat...
STPMIC25 latching
Hello,I'm in the process of moving from MP1 to MP2 on my device. The latter, used STPMIC1 that suffered the startup problem as described in AN5861 and I had to go thru a re-design to include the latching circuit on my PCBA.Can anybody confirm that th...

Chain STPM33 Clock
Hello,is it possible to cascade multible STPM33 Chips? That means SPTM33 + Crystal as master -> two STPM33 CLKIN-> Last CLKOUT -> two STPM33 CLKIN
Viper UVP when configured as high-side buck
Hello,We are using Viper31 to step down 250VDC to 12VDC in a buck configuration as shown in Figure 42 of the datasheet:This is also the same topology used in STEVAL-VP319X1B:We are working with STEVAL-VP319X1B to try to implement the UVP function wit...
UM2458 Inverter (SPC560P50L3 + L6491D): No Gate Drive on MOSFETs
Hello ST community, I am working with the STM UM2458 inverter board (5 kW low-voltage, high-current inverter) using the STEVAL-CTM004V1 control board with SPC560P50L3 MCU. I am configuring the system in SPC5Studio, debugging with UDE STK, and using M...
