Call for submissions: Only by daring to think and act can you understand true digital power supply! [Copy link]

 

Talking about digital power supply? Hot!
Making digital power supply? Difficult!
Analyzing the theory of digital power supply? Even more difficult!
It is better to do it once than to think about it a thousand times. This month, give yourself a chance to make digital power supply by yourself. Let's do it! There are also several like-minded friends to share, discuss and answer questions together.

July Call for Action: Dare to think and dare to do, to understand the real digital power supply!

Time: From now until July 31

Participation form: In the Analog and Mixed Signal section of the TI Technology Forum , with the title "Digital Power + Post Title", submit your own digital power design, and share the calculation process, principles and problem analysis . Design requirements:
1) TI chip is required as the core chip
2) A Buck or Boost circuit is required
3) It must be implemented digitally.
4) The output ripple is limited to 50mV to 200mV throughout the process. When this tolerance is lower than 3% of the output voltage, the output voltage is required to be 3%.
5) There is no limit on self-purchased development boards or proofing

I'm interested but don't know where to start. Is there any information I can refer to?

You can learn knowledge and win prizes, but unfortunately I have never worked on power supplies, so I don’t dare to start.
