Alex,
SPICE models, reference designs, app notes and EVMs are available within the product folders for LM5026 and UCC2897A. The UCC2897A includes a design tool calculator but the LM5026 does not have a calculator tool available.

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
I have a forward converter with an input range of 120-190Vdc. I have the UVLO set at approximately 115V. If I turn on the supply slowly, it works fine, seen in the first picture PIC 1. However, if I do a rapid increase, it turns on…
Part Number: LM5026 Other Parts Discussed in Thread: UCC2897A , What is the minimum operating frequency? The only thing I can find on the datasheet is the chart in figure 5 which shows RT vs Frequency with the bottom being 100kHz.
I have a design that I…
Part Number: LM5026 Other Parts Discussed in Thread: UCC2894 LM5026: the datasheet indicates 2 reset possibilities: P-MOSFET & N-MOSFET.
Plenty of examples for the P-MOSFET and it works.
Not a single example for connecting the N-MOSFET and any attempt…
Part Number: LM5026 Hello,
I'm debugging an active clamp forward converter using LM5026, with the following parameters:
Vin = 54V
Vout = 48 V
Pout = 250W
Inductor 240 uH
f_sw=130k
Cclamp = 30n
N mosfet : Infineon IPB117N20NFD
P mosfet: ON Semi. F…
1) I am planning to simulate the LM5026 IC's in TINA-TI simulation tool, but spice model not available.
Correct
2) Also we are looking to step up (boost) design by using step up transformer but existing evaluation board having only step down design…
Hi,
It looks your specs are different from PMP11478 which has 12V output but yours has 56V output. The transformer from PMP11478 cannot be used in your design. You need to redesign your transformer. So simple copy-and-paste from PMP11478 cannot meet your…
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 Other Parts Discussed in Thread: LM431 Hi All!
I have few questions regarding compensation in LM5026 and would be grateful if you could help explain it.
1. What does this COMP input impedance given in the datasheet refer to and could…
