Part Number: TPS40210 Other Parts Discussed in Thread: LM5020 Tool/software: Dear TIer,
I have project power spec as following
VIN 20V, VOUT 54V and 2A.
Concern the IC cost, I would like to know what topology have higher efficiency? please help us to…
Part Number: LM5020 Tool/software: Hi,
Vin=36-75V
Vout1=12V
Iout1=1A
Vout2=12V
Iout2=3A
Fsw=100KHz
We are using the LM5020 as a flyback converter. The MOSFET seems to be trying to turn on during the off period, and the voltage across the drain-to-source…
Part Number: LM5020 Other Parts Discussed in Thread: LM5022 Tool/software: Hi team,
This is FAE Jayden, my customer would like to know can they use 9Vin in their use case? From the datasheet, VCC may go blow 6V when Vin is lower than 10V. I just wanna…
Hello Pooja,
Thanks for your answers.
The fact that VOUT2 is always stable at 12V shows us that the feedback loop is working fine and no matter which load you apply on which output. The regulated output VOUT2 is properly handled by the controller.
Output…

Hi Sir,
This is Raj from XOMobility. I am currently working on an automotive DC-DC flyback converter project with an input range of 24V to 100V and an output of 12V/10A (120W). I would like to confirm whether the LM5020…
Part Number: LM5020 Tool/software: We designed dual output using 5020 as per the below circuit.
We are getting out regulation across V2out but same 12V not able to get across V1out. Voltage drop is there when converting 12V to 5 using any 5V regulator…

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: 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 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…
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…
