PI Forums

Hi there, i had made a design with the Inno2003. It works well und was also tested. Now the first 1k of electronics are build and during a long therm test some electronics gets problems. I checked the electronics and findout the power supply is not ok. The Inn2003 works

Hi, I have a question Concerns about power I have a 1976 Volkswagen Beetle that is fuel injected. My problem is that it will only start if you jump start it; it has a fresh battery. I'm not sure if the negative battery connection leading to the body is faulty

I designed 50W power supplu with PI suite. I used AOD2544 (Alpha & Omega) as SF with INN3679-H606. I need an alternative FET. the design parameters: Universal input (85-265VAC), 24V/2.1A output. Thanks, Imad Kastantin

Hi, Do you think it will be OK to do a LNK304 design for Buck....24Vout, 225mA output, with VAC input = 100-265VAC? I noticed all the App notes show 12V output.

Hi, Do you thinkTNY28X can be used for a 15W offline flyback with all PTH components? Or will the lead inductances mean too much noise in the layout? (It must be in PTH as its on a 4kW main board which bends due to big transformers and heatsinks, and so

Hi, I noticed RDR-737 uses a non shielded inductor. As you know, the inductor comprises the switching node. As such, why has a non shielded inductor been used in RDR-737 (The RLB9012 series). Also, why does the LNK302 datasheet say that any standard offthesheld inductor will do. as long as

Hi, We are doing a Buck using LNK302 for 100-265VAC to 5V, 100mA. Which offthe shelf PTH inductors are recomended?...as you know, the voltage across the inductor can be as high as 370VDC when ON, so are there any inductors offtheshelf which are not recomended? I see the RLB9012 family

Hi, We want to do a 5V, 100mA circuit from 100-265VAC with LNK302. The datasheet says a dummy load is required if an opto isnt used...it shows 3k3 being used when vout = 12V.....so , thats 44mW....so presumably, if we make output = 5v , then a 560R dummy load

Hi, I just looked up DPA422PN but its out of stock practically everywhere. Findchips.com shows only 53 in stock anywhere in the world. Is this part still being produced?

Hi, Is the LNK302 ok for doing 100-373VDC to 5V, 100mA in Buck configuration? (None of the App scms shows 5vout). Since it will be in CCM, (due to minimum on time of 475ns, do you agree this will need a SiC diode (which means a TO220), since <35ns diodes
