Discuss power management solutions. Ask questions and find answers on voltage configurations, short circuit protection, and programming.
Input is 300 to 800V DC and output is 24V DC. Attached the schematics of the same.
Although for 3 different batteries we managed to get the expected SoC and duration of battery discharge, we are facing difficulties in getting the expected discharge time for a fourth battery type. We followed the same procedure used to characterize ...
We need to use the Busy line as an interrupt and have noticed that often there is considerable switching noise on that line, making use for that function unreliable. We currently pull it up to VREG with a 39K. We have tried reducing this resistor to...
I am using stall detection when stepper motor enter under force. but temperature affact detection system. I am using same force in same system but stall detection feedback is different position in different temperature. I need to find force position...
I have designed a ballast to reduce DC voltage before the power supply driver (UCC28880).This ballast was first do with MOSFET 1200V : it was OK. We decided to replace the MOFset by IGBT (STGD5NB120), and then the ballast generates noise ( like crak...
mode 1：SW pin short to GND or VDD，how to short ？connect direct or use resistance（what is the best value？）， internal swith will not workmode 2 ：SW pin NC or connect to VM，but the internal swith is working still。in high temperature ，High efficiency ，L...
I am using ST1S03 in the inverting configuration shown in Design Note DN0011. Input 3.3 V +/- 7%. Output -3.3 V ~150 mA.I am getting efficiency only ~69-72%. Which, now that I look into it, is not much worse than the datasheet typical value of 70-75%...
Dear Members,where can I download updated version of :Viper Flyback Converter design software ?I checked the bom, but can not find the value of F1, Th1, C1 and L1, thanksScreen shot :
Hi, I wanted to start with this project for medium power motors of 20 30 55 kw. I have been checking in the community but there is little of this type of AC motors I wanted an orientation with which microcontroller to start and what tools to use for ...
As the topic says i want to implement double buffer for my ADC on DMA interruption to save data on SD card.I've done two buffors. I am saving data to two of them in sequence. If one gets to it's limits the other one is taking the data. To point the c...
