MC33063A: MC33063A related issues

Hello Jeno,

Please give us until the end of the week to review the schematic.

You could use power stage designer for defining the parameters of the design: POWERSTAGE-DESIGNER Design tool | TI.com

Best regards,
Brigitte

Hi Jeno,

Thank you for using E2E forums, below are my answers to your questions:

1. Could you please provide the design specs for the schematic that you have given? Vin(min and max), Vout and Iout?

2. May I ask why are you not opting for the LM515X devices or TPS40210? Here is a reference design with similar output voltage SEPIC design. https://www.ti.com/tool/PMP30162 or you can also have a look at this app note on how to design an isolated flyback using LM5155 https://www.ti.com/lit/an/snva866a/snva866a.pdf?ts=1706883705524&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FLM51551 

Please let me know if you have further questions.

Hi，

1. Input 15V, output 160V, 10mA, power 1.6W

2. The updated schematic diagram is shown below. Could you please help analyze if there are any issues? Or do you have any good suggestions?

Hi Jeno,

Please allow us some time to get back to you, I will give you feedback on the review of your schematics maybe end of this week or early next week.

Thank you for your understanding.
