PI Expert recommends to put a named C_SOFTSTART if the output voltage is greater than 12V o output capacitance is greater than 100uF. But looking into the Datasheet and examples I cannot find where this C_SOFTSTART is supossed to be placed. Designing a NON ISOLATED BUCK CONVERTER (230Vin-36Vout-5W). Thanks in

Hi, We use LYT1604 non isolated driver for our 22watt LED driver applications. We want to Turn OFF and TURN ON the driver externally using a LDR light sensor circuit (DUSK - DAWN Operation). Can you suggest a pin of 1604 to implement turn OFF/ON or any suitable method to

I am not able to view/edit my old Flyback designs from PI Expert online portal. I think this could be because of the website layout update from power Integrations. There should be 10-15 Designs in my Account, but now when I login, I see only 4 designs in the list

Greetings, I designed and build a power supply using PI Expert tool for general pourposes. After rebuilding it, i get rid of clicking sound, and now it works, but the output is at constant 3,2V, regardless of Zener diodes that i put into feedback loop. I tried loop as in

Hello Team, We are working on to design 24 V constant voltage output for driving LED String. We are using VAC - 110 VAC to 230 VAC. We can go with Isolated and non-isolated both architecture, as per availabilty of design. Please share proper part s and reference design.

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
