Part Number: LM5026 Other Parts Discussed in Thread: PMP22075 Hello guys,
One of my customers is considering using LM5026 for their new products.
Also they are considering to refer PMP22075(LM5026 reference design) . At this moment, they have the following…
Part Number: LM5026 Other Parts Discussed in Thread: UCC27511 , PMP22075 Hi Expert,
My customer follow the reference design PMP22075 to change a little bit then make LM5026+ UCC27511 to do.
and they find the no load Vds spike is high but turn on the load…
Part Number: LM5026 We are developing a telecom charger in which the input Vdc(V_bus in schematic given below in the figure) will be 400V. The LM5026 is being used to drive two N-channel Mosfets at a frequency of 100kHz. An active clamp forward converter…
Samir,
I am going to close this E2E thread since I believe we resolved your original inquiry. If you have any additional questions, please submit a new question with the appropriate part number or subject in the title? Thanks for contributing to E2E. …
Part Number: LM5026 Hello!
In the COMP pin there is a current mirror that replicates the current flowing into the COMP pin from optocoupler's phototransistor. (page 14 of the LM5026 datasheet) I have two questions. What is the purpose of using this…
Part Number: LM5026 Hello all!
I am using LM5026 for operation and control of single switch forward converter. We have designed the resistors for oscillator frequency and duty cycle clamp using the following configuration mentioned in the datsheet.

Part Number: LM5026
Hi,
I am wondering how can I improve no/low load efficiency of my ACF converter with self-driven synchronous rectifier? It is a 280W converter at 200KHz with good efficiency in high loads. I could reduce the no load power loss from…
Part Number: LM5026 Hi,
We are optimizing our low side active clamp forward converter with synchronous rectifier and the following figure shows the VDS_Qmain (Ch1), VGS_Qaux (Ch2), VGS_Qmain (Ch3) and the current from clamp capacitor to Qaux (Ch4). I…

Hello TI expert,
There is a oscillation (about 16 KHz) on switching node voltage amplitude (yellow) in our low side ACF converter prototype. Is there a fundamental reason for such an oscillation there, since we tried quite a few things…
