SPV1050 input current specifications
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...
Flyback with VIPer26: Snubber overheats, but no visible Vds spike. Low Vout.
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...
Is it possible to develop a 150W, AC85-264V power supply unit for LED lighting using HVLED001A?
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...
L6494LDTR
Hello I am using the L6494(14PIN) as a driver for a high and low side FET in a half bridge arrangement. My DC volts can be anything from 120Vdc to 220Vdc. and current up to 17AIs there anyway to determine the breakdown mechanism if I do not momentari...
Resolved! discontinued eval for STWBC86 P transmitter
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...
Resolved! ECMF4-20A42N10 vs ECMF04-4HSWM10
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
EVALST-3PHISOSD question
I'm considering developing it with that kit.Can't I download the circuit diagram and firmware file?
Controlling iq in a PMSG
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...
Resolved! ST1PS02 - Impedance of logic inputs D0 D1 D2
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.
