Infineon makes a full bridge EconoDUAL module, F4250R17. PI makes plenty of gate drivers for the half-bridge module. Are there plans or designs for a dual- or quad-channel gate driver to support this full-bridge EconoDUAL package? Thanks.

I am using LNK626 as a flyback converter. The output is Non-Isolated 5V. So can I use feedback from DC side instead of AC side of the output diode? I think I will get better regulation, because diode drop variation will be eliminated.

Hi I am using the above Inn3678 for a 60W power supply, from a PFC which will supply 385V nominal. The main output is 12V I did not initially realise that the SR gate drive was only 4.5V so had a MOSTFET which did not turn on well enough at

Hello, I'm trying to design an power supply with one isolated output and 2 non isolated. Using LNK6763V Universal Input at 60Hz Isolated output 5V 200mA; Non-Isolated/Bias 15V/250mA - It Supply a MOSFET Driver used as phase cutting; Non-Isolated 5V 100mA - Supply an auxilary circuito to indicate failure and

Hello Sir, I have made 2 design which i have put this file below.But unfortunately, although their output turns are same, the input turns are different.Which one I must choose?And why there is difference between them?And also I wonder, how it is possible in the 5V output voltage with 4

I'm using LNK3307 in 5V 0.5A power supply with zero crossing. I've based my design on the RDK-877 Reference Design Kit. The zero crossing is only accurate for the negative half cycle of the Ac but triggers early for the positive half cycle. Please see the attached ZC_Osciloscope image. See

The comments refer to Gerber data generated in this project. Discrepancies in the generated Gerber data will be addressed here. First of all, I should point out

Hello, I am attempting to repair a Fridge CPU (KG36VVL30S.11). It had the resistor fuse blown and the LNK304GN shorted. Replaced both with local store part but still not working. Checked all caps and resistors from the flyback and all checked good. The polarized caps are with low ESR (~1ohm

你好！ 我使用TOP258YN设计了一个隔离式反激式开关电源。下面有原理图。 它是220VAC输入，75V输出，大概10W左右的设计。它的输出是作为一个反激式升压电路的输入，这个反激式升压电路是将75V升压到3000V。 我的问题是：在反激式升压电路输出3000V的时候，75V的电源会损坏TOP258YN，请问我应该如何解决这个问题？ Best regards

I have an SMPS where the TOP244PN switching IC is used to power the standby section. Is there any alternative in the TNY switcher series I can use in its place? Also, can I use the TOP244YN package in place of this TOP244PN package? It seems in the PN package
