Part Number: LM5020 Tool/software: Hi,
I am designing Isolated DC-DC converter using Flyback topology with LM5020 PWM controller, could you recommend reference documents related to Flyback transformer design and
PWM controller with similar features to the…
Part Number: LM5020
Dear Team,
It needs to have LM5020 on boost application schematic with below condition by our customer. Do we have suitable reference design?
Please help comment for our customer reference.
Vin: 48V
Vout: 54V
Power: 30W.
I only…
Part Number: UCC28700 Other Parts Discussed in Thread: LM5020 Hi,
I am looking for a PWM controller similar to that of UCC28700 / LM5020 but with <50kHz switching frequency.
Reason : My operating input is 50V-1500V and so the minimum ON time of the primary…
Part Number: LM5020 Hi ,
We use LM5020 as flyback convert ,
Vin Max is 60V ,Output is 10.4V 1W ,Fsw :450kHZ , CS pin resistor is 0.9ohm
Flyback has 3 output ,the voltage is both 10.4V , Voltage feed back from the Auxiliary source .
Our test condition…

Other Parts Discussed in Thread: UC1842 , LM5020 Previously, I was using UC1842 IC. There is any no problem from it.
I want to use LM5020 integrated, but where should I connect the sync input and shutdown points? I want to use my ORCAD Pspice Project.
Part Number: LM5020 The problem is as follows. We use the LM5020-2 as a flyback converter 24V250V/15mA. The flyback converter is actually running, but we have a subharmonic oscillation with f_sw/2 on the signal. The duty cycle changes with half the working…
Part Number: LM5020 Other Parts Discussed in Thread: LM5155 ,
I carried out the design as shown in the picture. However, the simulation does not work smoothly. Please review whether the designed circuit is a normal circuit. And I would appreciate it if you…

Hi
The attached picture is a block diagram of LM5020.
I want to know the current sense amplifier gain, which is the marked part.
Thank you
