Good morning I tried making a USB Charger Power Supply using LNK6448 among LNK64x4-64x8 LinkSwitch-3 series. It works just fine by making it the same as the Applications Example. But this product has poor power factor and THD (Harmonic A), is there any way to secure it? If yes, please

Hello everybody, Recently we have achieved some TOP260YN and almost none have worked. After we bought another components from other suplier and all of them have worked. Comparing both, we detected that the resistence betwen pins S and G were diferents. In TOPs good, the resistence betwen pin S and

Hi I am using a INN3760C for a 24VDC 100W power supply. I had a lot of emmissions over the air because the INN3670C was switching into the continuous conduction mode and back between 1-3A load. from 3A to 4A it was ok. Then I placed 100Ohms and 2nF in

Dear PI team, We need +/-12V in our project. Can you please suggest the circuit/ design documents which can give 12v @ 500mAmp(minimum) and -12v @ 100mAmp(minimum)?. input voltage is 230vAC @ 50Hz. Best regards, Sateesh

Hello, I have a customer that is asking about the specific differences between the TOP234Y and the TOP234YN. I believe the "N" part is identical, but RoHS compliant. Can you confirm, or advise further? Thanks.

Hello, I start to design on INN3672C. In my application, I need 11V, 700mA output (+/- 100mV ripple volt is ok) and input volt will be 200V AC to 265VAC. There is no power constrain on mains input. My question is 1. what is the role of the primary bias

Hi, I am wondering what the minimum load requirement for the no-neutral designs are? https://www.power.com/community/videos/no-neutral-smart-wall-switch-linkswitch-tn2 AND https://www.power.com/design-support/design-examples/der-832-two-wire-no-neutral-wide-range-isolated-flyback-bluetooth-wall-switch-using-linksw… Thanks!

Good day, all New being here, I'm using a PCA9685 with a pinout board like Adafruit's. I'm trying to run a bunch of LEDs at 20 mA, and the chip is supposed to be able to source 10mA and sink 25mA. I understand that to have it Source, connect the

Hi. We intend to use InnoSwitch4-CZ in our next project, but, by now, there isn't any development kit available on the P. I. site... Additionally, we can't find any component in any distributor... So I wonder if it's better to wait a while and, yet, use InnoSwitch3 in this project

1. We need to design a 65W laptop adapter with different output depending on feedback resistor by keeping rest of circuit same. Output voltage requried are: 15.27V , 19 , 19.8V, 20V or 20.67V . 2. We selected this IC: https://www.mouser.com/datasheet/2/328/topjx_family_datasheet-11851.pdf 3. On its page 15, a reference design for
