isolation

Hello all, I want to create a solder-mask keep-out area in Altium designer 22 as in the below image. I tried using a polygon on both the top and bottom solder mask layers but I got this: Is this how is supposed to look in 3D view? Is the method I used the correct way to create solder-mask...

Hello all, I have been checking the EVAL-ADUM4146 evaluation board for the ADUM4146 gate driver. In this board, they are using a (2W, +15/-3, +93/-185mA) isolated DC-DC converter module which is the R12P21503D. And in the gate driver datasheet, it says: 11 A short-circuit source current (0 Ω...

I am developing IoT device using ESP32. I am using ESP32 along with ADS1115 for voltage measurement of my equipment. My electrical device operates with following parameter : ~0-5 V DC , 25 Amp with constant current mode adjustment prior to operation. I want to measure this voltage change...

Hi to all, I'm desigining a PCB with an Eurocard size that will be used in a subrack. The board is connected to a mother board internal to the subrack and have some connector on the frontal side. On the frontal side, the boards are covered by a metal front panel (chassis) that will be connected...

Hi everyone; I'm doing a reverse engineering for thermocouple system that works in specifique condition (temperature=300°C), knowing that the originaly systeme use the material below in the figure for covring the battery and the pcb. I have already finished the electronique parts and the pcb...

Hey folks. I’ve been working on a home project involving a low power AC/DC converter based on the power integrations ref (https://www.mouser.com/datasheet/2/328/rdr623-1487555.pdf). There were some minor changes, I added a current limiter to keep to spec, and in addition the circuitry has a...

Hi, I need to design a DC DC Converter Circuit: 48v to 12v DC 10A Max Current with Isolation. Anyone, please share reference design/Schematics if any.

I am looking at some PCBA's with ethernet RJ45 connector regarding surge test susceptibility. Common legal requirement are 1.5kV isolation. The first issue that I see is PCBA's with RJ45 connector metal housing grounded to logical 0V (ground plane). Like Raspberry PI for example. Look at the...
