Part Number: LM5023 Tool/software: Hello,
I am currently working on a high voltage flyback design. I have the circuit working well, but during testing we have encountered an issue that isnt ideal. When we execute a short on the output (UL Testing), we…
Part Number: LM5023 Hi,
I tried to design a flyback converter using lm5023 with following specifications,
Vin=500 - 750 V
Vout= 5V, 5A
But when I enter these parameters on webench power designer it shows design cannot be created due to some reasons. I…
Part Number: LM5023 Hello.
My name is Eunseok,
I have a question while looking at the block diagram of LM5023.
I know you're busy, but could you answer a few questions?
1. In soft start operation, there are two n-channel mosfets inside, but isn't…
Part Number: LM5023 Other Parts Discussed in Thread: UCC28704 , UCC28750 , PMP20771 , PMP40144 , PMP30720 We are looking into low-cost high efficiency Isolated / AC to DC / DC to DC converter for 18-40V AC/DC input to 5V @ 1.5A current. Kindly suggested the…
Part Number: LM5023 Hi there,
i wanted to use LM5023 for non-isolated two-switch flyback. i have some questions:
- i wanted to use Webench for calculations but it won't work. Vin: 600 - 1500V; Vout: 24V & Iout: 1A.
- generally, do you suggest…
Part Number: LM5023 Other Parts Discussed in Thread: UCC28600-Q1 Hi,
Is LM5023 automotive grade ? If not please suggest automotive grade version or alternative for LM5023 and kindly provide the unencrypted SPICE model for the same. Please consider this…
Part Number: LM5023 Other Parts Discussed in Thread: LM5021 Hi
We are using LM5023 in our design.
I need to build a 19V,3.3A continuous mode Medical Grade power supply.
For continuous mode of operation what are things to be considered while designing…
Part Number: LM5023 Other Parts Discussed in Thread: TL431 Hello.
I have a question about the driving principle of the PWM comparator in the datasheet block diagram during Flyback design using LM5023.
1. Could you tell me how to turn PWM ON and OFF?

Part Number: LM5023 I need help with the following question. How to calculate RCD snubber for Quasi-Resonant controller, the application note AN4147 explained very well but fixed frequency. Quasi-Resonant with no load, the frequency is around 60KHz, but…
Part Number: LM5023 Hi
I am planning to design a 19V,3A open frame adapter.
In this i am going to use LM5023 IC.
I have a doubt on how to choose the resistor for OVP on QR pin.
Kindly suggest a idea to calculate the resistor for R1 and R2.
In the Datasheet…
