Hi evertone, I'm using the TNY286DG-TL chip along with the PI EXPERT tool to design a 12V/1A power supply. I've created a diagram, but I have concerns about the transformer I'm using. My question is: Will the design I'm showing below work correctly at 220VAC @ 60Hz?

Hi, We are doing a 130W Two Tran Forward with vout = 24V. It will power two other isolated SMPS's , so that they can give their isolated outputs, as well as giving a 24V, 48W output itself. Is it true the HiperTFS cannot be used with vin

So I have to repair an ac/dc adapter utilises a TNY278PN chip, but the problem is it's decapitated (exploded), and the title part of its case has been lost. But the man who teardowned the device, just after incident, SAW that now missed part of the case, and put all

I want to ask about how the Integrated circuit decides the proper (di/dt) for next cycle , the voltage across an inductor/transformer is L*(di/dt) the Integrated circuit TNY289 as I understand it ramps up current so that (di/dt) is constant and consequently the voltage across an inductor/transformer is constant during

Hello, i tried to set the "response time" Tax according to the manual page 13 to the minimum with 100pF and 24kOhm. I got ~6 to 7 us "response time" for the Vcesat desaturation detection (with sense diodes). I used the application proposal Fig. 8 (also on page 13 -

I am trying to design a simple power supply using TNY268 , I connected the circuit as in the attached schematic Where the input of the attached schematic is connected to the output of a bridge and smoothing capacitor , I understood from the datasheet that at the beginning of

Hi i'm currently designing a power supply that can work with inputs of 24, 48, 120 and 240Volts For this purpose i'm using different transformer ratios, one for 24-48 and another ratio for 120-240 I haven't seen a design with an input lower than 85 VAC, but i read in

We are building a 7W led driver based on LYT0006. We constructed the circuit based on A17/A19 LED Driver Lamp Replacement document. observations + Rectifying and smoothing part is working well . It is giving 320V . (for 230AC) + When we connect the rectified 320V with LYT0006 ( BUCK

Greeting, We're looking at the evaluation boards DER-977, DER-978, and DER-984. However, we weren't able to find the design report or application note for the latter two. Do you have these documents available to share with us? Regards, Alex

Hello, I am using Link switch-HP (LNK67xxE) for 10-35W flyback converter designs. We have multiple designs with different input voltage ranges and output power level. Designs are generated using PI Expert & PI Xls , these designs are working fine with some iterations of feedback and programming resistors values. However
