I am trying to build a buckboost converter for converting 5-40v input to 5-35V output at 3A max to use it for many purposes by usign TL494. I am using a SEPIC topology as i want a non inverting output. I simulated the circuit in proteus. The circuit works fine when i connected a 500 Ohm load, I...
I'm building a board with multiple ASIC's in series. Each ASIC has a footprint similar to a DFN, where there are a few IO pins on either side of the ASIC. In addition there are two large pads that supply power (V+) and ground (V-) for the high-current domain. Further, these ASIC's are...
I'm working on a remote start system for an older gm diesel vehicle and so far everything has worked great, but I've hit a stump that I just cant figure out.
The engineers who designed the ignition switch of my truck though it would be a good idea to run starter solenoid power though the...
Hi,
Usually most of the PCBs have solder masks but recently i have seen a PCB with only few tracks(high voltage/current) with solder mask open. when do I have to keep the solder mask open for traces?
I'm working on a DIY project where I need to control some 9V solenoid valves with an arduino. I don't have the tools to make a PCB myself, so i choosed to work on perfboards.
Now, I have to connect power supply (MeanWell ) to the step down regulator (Polou D36V50F9) that powers the solenoid...
Hi All,
For my work it is becoming more common for me to measure lower, and lower resistances. Megger has a really good manual on how to measure down to micro-ohms (for example to determine the quality of bus bar joints etc). I have found the 4-wire measurement to be very repeatable, and useful...
