Posted on November 07, 2017 at 22:32Hi there,I would like to design a led driver to supply a load of 100W and 150W using the HVLED001A but the eDesignSuite is not calculating the right transformer. According to datasheet of HVLED001A is possible to ...
Posted on October 31, 2017 at 00:52Hi,Please see schema below.With this circuit the cells in series are creating ~ 0.82V in office lighting.LDO2 output is only 0.5v. This does not seem right. :)Can anyone at ST help with correct selection of R1-6 s...
Posted on October 26, 2017 at 09:18The output Voltage expected is 6V and output is constant for 110VAC input. But the output is turning ON/OFF for 220V input. Please let me know to resolve this issue.
Posted on January 10, 2017 at 10:59Hello!Has anyone worked with the STEVAL-ISW001V1 demoboard or has designed an inverter welder based on the demoboard schematics? My design is working well in normal operation but I have some issues with the short-c...
Posted on October 20, 2017 at 14:16Hi,I'm repairing an audio power amplifiers from a top model manufacturer like Harman-Kardon, Dynaudio, Bose from cars. And in almost all of models I faceing up with broken regulator L5973. The failure is that the v...
Posted on October 16, 2017 at 21:17Hello,I need to find suitable alternatives to the VN7140AJTR that can swapped in with zero board changes.Is there a complete list of replacement parts available?It looks like the VN7040AJTR is a pin compatible repl...
Posted on October 19, 2017 at 09:15HI,I have to build a 3KW PFC. The main points are:- 3KW- AC and DC operation- Analog Design, no SoftwarePreferd:- CCM- InterleaveIs there an expaple how to use 2x L4981A wit extrnal out of phase synchronisation and...
Posted on October 16, 2017 at 11:00I have three doubts about if L6482 regulates the torque when we use STCK input:- If I use this STCK input, does torque regulation run? i.e. Does L6482 regulate torque using R Sense etc, when I use STCK input instea...
Posted on June 19, 2017 at 15:28HI!I am evaluating a bldc driver setup for a golf caddy with the stspin3201 eval board. The motor has Hall sensor, so I would like to use it, as the main (and preferably) only sensor. Is it a good idea not to use FOC,...
Posted on October 09, 2017 at 15:41I have successful compiled the FOC AC6 STM32F4xx_UserProject corresponding to my 40V BLDC motor with Hall sensors. However, I always get a Hard Fault during 'MCboot' as shown in the attachment.I am quite new for mo...
