Hello PI Engineers, always great reading these help topics. I need your help again. I am using an LNK304DG-TL chip with a 680 uH output inductor to have 100 mA output load. I am seeing 456 mV of ripple on the output. I am measuring with a very short ground

How the TOP264 device will support 18V input voltage

Hey, we have a CCTV setup at our property. The property doesn't have a direct electrical connection. It is a warehouse, and there won't be any activities during the nights. So the only electricity needed is for the CCTV system. The place got the system installed by some CCTV services

Hi, Good day. My customer would like to request the pad dimension recommendation and back dimension for PN#LXA03B600. Could you please help to check and advise? Thanks. Kent

Hello all. I have since prototyped a circuit that allowed me to create a negative rail from one single, positive output. The transformer was designed to produce only one positive output. By rectifying the negative portion of the output switching waveform and filtering, then zener regulating, a low current (10

Hi there... I'm using a LYT1604 in a low-side buck 20W 60V integrated LED PCB driver. Some of the units are experiencing a turn-on delay of between 1 to 5 seconds. Once they start they run at the correct power level. The circuit is as per Fig.1b in LYTSwitch-1 datasheet

I’ｍ considering replacing INN3168C-H107 with INN3270C-H217. When only the ICs were replaced on the same board, the INN3270 was operating at a lower frequency than the INN3168 even under the same input / output conditions. What is the origin of this difference?

Hi Power Integrations Team, I would require your suggestion and advice for intrinsically safe transformer construction as required to pass the explosive environment IEC 600079-11 standard. This standard is applicable to systems used in the Oil and Gas industry in an explosive environment. I have designed a SMPS power supply

Hello, I used the PI Expert to calculate a flyback design with the InnoSwitch3-EP. I have some trouble to understand the results of the magnetics designer. Doing the windings is no problem,but I don't understand, which core I have to by and how to "Gap the core halves to get

We designed the power supply circuit shown in Fig. 1 using TOP253EN. As a result of the test, it was found that there was distortion in the output voltage waveform at startup.(Fig. 2) What could be the cause? Please let me know.
