i have seen Vds of TNY267 is taken as 4.41 but in the datasheet i have didnt got this information how primary nominal inductance calculated

Hi. It's about an InnoSwitch3-EP use in a three isolated outputs power supply. (As these outputs are isolated from each other, I suppose InnoSwitch3-MX + InnoMux pair cannot be used.) A specific problem occurs when one of the secondary outputs has a heavier load than the main one: under this

Hello. I would like to design wide dc input range DC/DC Conveter using InnoSwitch4-CZ. The requirement of input voltage is DC 80 to 380V Is it possible or not ? Best regards. Hwang.

There have been numerous additions to the PI product line in the past 3-4 years. Looking for a high efficiency (90+%, ideally 95% or higher) high voltage (300-500Vin) to low voltage power supply controller. Some of the new products advertise Power Delivery (PD), wondering if it those are easy to

Hello, I`m the student developer interested in Innoswitch -pro Series and trying to develop product with INN3376 and INN3378. I used the UPD301 and hlk7628 for microcontrollers, and worried about Voltage and Current problems. So I searched the forums. My big concern is this 3 thing. 1.In the datasheet and

Hi Sir/Madam , Possible to suggest how to Reduce Output Noise at secondary, although I had add Pi Filter Circuit at Secondary output. Signal as show in the attachment .

For example, 24V direct current is converted into 220V alternating current, how much alternating current is needed to convert 1-degree point?

Hi guys, I have designed an SMPS power supply using TNY290. The PS has 2x20V, each rail with 1A current capability, so in theory up to 40W, but in reality 36W. The power factor is quite poor here, believe it or not, it goes from 0.3 when it is in

Dear expert， Thanks for your rare time，Using LNK4114D design output specs 12V 1A，What is happen when SBD and VCC pin is short ？because Don't find abnormal situation at test line 。Thanks!

HI, The power supply(12v,5a/10a) is working but there is a voltage problem. When no load is connected, voltage becomes 1v above and when load is connected it goes to normal value. Please guide me and tell reason for this behaviour. Thanks Rejith cv
