Hi, Please do the following soak tests on Hiper-LCS2 so we can see how it performs? Do repeated short circuit output test, over and over again. Do start-up into short circuit, over and over again. Do start-up into 200mF of output capacitance, over and over again. (48V output and max

Hi, We are facing a situation where there is a relatively large loop between the drain pin of the InnoSwitch-3-EP (INN3679C) and the transformer’s switch node. Since the transformer’s switch node is located at the center pin, it’s not possible to minimize this loop effectively with the current placement. To

输入电压180V，TNY279PN在输出功率达到3W时保护，但是我看TNY279PN的规格书功率可以达到12W，请问如何提高功率限制？

I am currently working with the RDR-1002 140W USB PD 3.1 Extended Power Range (EPR) Evaluation Board, which includes the InnoSwitch5-Pro (PowiGaN), HiperPFS-5, and the Injoinic IP2756 USB PD Controller. I would like to perform testing and control operations on the InnoSwitch5-Pro through the IP2756 PD controller. However, I couldn’t

Hi, The HiperLCS-2 controller is an LLC controller which features all the control and primary FETs on a chip...and it has a sister chip which does synchronous rectification for this LLC controller. It does the synchronous rectification in a highly reliable manner using secondary side control and a noise-immune "fluxlink"

Hi, We wish to do a 100-265VAC input PSU with 52Vout and 420W. We need it to be fanless. Enclosure is metal with vent holes. We wish to have a BCM PFC chip into the HiperLCS-2...and have three of such (BCM PFC + HiperLCS2) in parallel...and have a load share

Hello, We are using two 2SC0435T2F1-17 driver modules to run four FZ600R17KE4 IGBTs in parallel, with each driver channel controlling a single IGBT. These IGBTs are connected to the primary side of the transformer. The system is designed to withstand arc events on the secondary side of the transformer, with

Hi, We are implementing the DER-865 design for a phase control dimmer. And I have a few questions: Is the overcurrent protection, also implemented on the high voltage side? So if the connected load on 230V would go from 200Watt to 600Watt for instance? If not, do you have any

I’ve designed a 9W, 12V power supply using the INN3624 (1250V version). When powered at nominal 240V AC under no-load conditions, the resistor connected to the FWD pin burns out. However, when the input voltage is reduced to around 70V AC, the resistor only heats up and the output voltage

Hello. When INN3670C is working, the following picture is observed. Blue - constant voltage at the output. Green - Voltage on the secondary winding of the transformer. Uout = 24V Iout = 2A. The transformer is standard POL-24219. What could be the problem?

I am currently working on a project that involves a Fuji Electric IGBT module, model 2MBI600VN-120-80 (1200 V / 600 A, dual 17 mm package). I am considering using one of your SCALE-2 plug-and-play drivers, specifically the 2SP0115T2B0-12 or an equivalent model suitable for this IGBT. I would like to

I am a retired electrician with a strong background in electronics and enjoy repairing equipment I’m not a design engineer but enjoy reverse engineering to identify problems. I’m repairing a Lincoln MP210 welder circuit board and having trouble identifying a faulted Power Integrations component in the TOP 264-271 family. It

Dear Sir, Can Innoswitch 4-CZ design for dual output? If yes, would you please provide the detail? In PI expert simulator, we cannot add more than one output in the design for nnoswitch 4-CZ Thanks Derek

we love to use 3D files for our altium designs is there a good and nice STEP file we can have ?

Hi all, I'm working on designing a compact ACDC power supply using InnoSwitch3 or similar. My input is universal mains and I need two outputs: 15V 1A non-isolated, referenced to primary 5V 1A isolated from mains and from the 15V rail Can I generate the 15V non-isolated output from an

Hi. I recently got a design for a automation project created with the online designer based on a TNY290. I have made a prototype based on this design, and it works great with the a stable voltage output as per the design. However, I have been trying to get rid

HI Team, I am currently using TOP270EG IC for my current new design SMPS. I am facing startup issue. Unable get IC power on. Note : I am not used PI design given transformer spec , Instead of I used another one flyback (65Khz to )transformer which is used our

Hi, We have already tested the INN3164C-H10 in a Flyback design with the following specifications: 430V max. DC input voltage 5V/2A output n=10 (Npri/Nsec) - Transformer's turns ratio According to the datasheet's page 30, the maximum RMS working isolation voltage is 460Vrms and the creepage is 11.4mm. However, we need

Dear PI Team, since we're not having any luck getting acceptable results using a LYTSwitch-5 Circuit based on DER-515 and have determined the transformer to be the cause of all our issues, we wish to switch to a transformer-less circuit, but using the same driver (LYT5228D). I found the DER-596

Hi Team, We are developing an isolated flyback converter with a nominal input voltage of 24 VDC and an output of 18 VDC, delivering between 20 W to 30 W of power. In a related project, we have used the InnoSwitch3-EP family successfully. I initially considered using the same family for this design; however
