Part Number: PMP4862 Dear all,
In pmp4862, G095026LF flyback transformer (Mfr:GCI) and coupled-inductor L7 UU15.6V-252LF (Mfr:GCI) adopted. However, I can not find them in RS, digikey or Mouser. Where can I buy them? Or is there any substitution for them…
Part Number: UCC28810 Other Parts Discussed in Thread: TL431 Hi sir,
Im designing a transformer with reference to PMP4862. I have the following issues,
1) The current sensing resistor R24 is burned each time i increase voltage.
2) The secondary auxiliary…
Im using PMP4862 as a reference design for my thesis. I noticed that the schematics and the PCB dont match.
Im you take a look at these to images, at the PCB U1, R17 and Q4 are connected to each other. But on the schematics on the other hand, U1 is only…
Hello Mohitha,
Sorry for the delay. I only got his information today, and have limited access to email this week.
Here is a listing of the signals on the control connector:
Enable : Active high enable signal. Turns LED driver ON/OFF by driving the gate…
Part Number: UCC28810 Hi sir,
I was designing an LED driver circuit with reference to PMP4862. But I couldn't find the information about the transformer T1. Can you help me find the information like number of turns, AWG of primary and secondary winding…
Hi, I'm working on a project in school were I have circuit PMP4862 ( http://www.ti.com/lit/df/slur512/slur512.pdf ) as a reference. Unfortunately is the flyback ( http://pdfcast.org/pdf/125-w-flyback-transformer ) no longer available. I wonder if you…
