Part Number: LM5026 Dear Expert
Could u hlep to review the sch ,many thanks !
Could u hleo tell me after lowering the two legs, the SS will also discharge internally, right ？
Part Number: LM5026 Other Parts Discussed in Thread: PMP22075 , , TL431 Tool/software: Hello,
I modified the circuit design of LM5026 based on PMP22075, but found that Pulse transformer (T6) makes noise when powered on.
The following are the specifications…
Part Number: LM5026 Hi,
Modify the TIME resistor and connect it to REF (R16 NC, R10=100k ohm) as shown in the figure below. An abnormality of the VCC power supply occurs.
If R10 is changed to 33k ohm, the VCC is normal.
please help confirm

Part Number: LM5026 Other Parts Discussed in Thread: PMP11478 , , UCC2897A Hi Sir,
could help check this schematic is correct? or any suggestion to us, thanks for you support and from you learn.
in addition, how do we calculate the turn ratio and…
Part Number: LM5026 Other Parts Discussed in Thread: LM5025 Hi，
Can the PSPICE model of LM5026 be imported into TINA for simulation?
Does the LM5026 have a TINA simulation case of the already designed DCDC converter like the LM5025?
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…
Part Number: LM5026 Hello!
I have a question regarding the gate drive output section in LM5026 while driving MOSFET in single switch forward converter. During turn ON, the gate drive charges the gate source and gate drain capacitance of MOSFET through…
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…
