Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Hi! We have designed a custom board using STWLC38 but its not working. We also have the Evaluation kit of STWLC38 and Im using the same coil to test my custom board. Im getting roughly 0.6V at VRECT pins after nearly every second. I aslo have attach...
Hi,I am working with a battery pack and the BMS. I have connected everything correctly to the board and after a first run everything seemed to work properly, the board was receiving commands from the MCU through the translator ISOSPI, and the green l...
Hello,I am planning to use the SPV1050 in buck-boost configuration.According to the datasheet, in this mode the charging current (I_batt) has a minimum value of 30 mA.I have two questions:Why is this specified as a minimum value? Can the actual charg...
I am debugging a VIPer26-based flyback converter designed, which fails to regulate and is stuck at a lower voltages. The primary issue is a severely overheating RCD snubber resistor, indicating excessive power dissipation. Paradoxically, the Vds wave...
Edited by ST moderator. Please use English language in this community. HVLED001Aを使用して、150W、AC85~264V、力率0.95のLED照明用電源ユニットの開発は、可能でしょうか? 可能な場合、効率は、どの程度になりますでしょうか？ 参考回路例等がありましたら頂けませんでしょうか？ 電源ユニットしては、非絶縁でもOKです。 150W品でコストをできるだけ安くするには、どのような方式が良いか、制御用ICも含め...
The STEVAL-WBC86TX eval PCBA and the associated GUI appear to be no longer supported. Are there recommendations for proceeding to design with the STWBC86 Wireless Power Transmitter, without them?I am getting started with the AN5961 Wireless P Xfr Coi...
Hello, Please confirm if ECMF04-4HSWM10 is possible replacement for ECMF4-20A42N10? ECMF4-20A42N10 is in LTB status and we need replacement part with "recommended for new design" status.Thanks,Quynh
I'm considering developing it with that kit.Can't I download the circuit diagram and firmware file?
HelloI want to control the torque of a PMSM (from a small micro-turbine). I guess that I should use FOC. I have found a Low-voltage high-current inverter motor board UM3489, but I do not know if it can be used for generators. It seems that it only wo...
Regarding ST1PS02. Which is current drained from logic inputs D0 D1 D2 when connected to Vin?Is it safe to pullup them to VOUT, i.e., can it cause startup issues?Thanks for the attention.
