[MPS Mall Mini Program is online with huge discounts] Buy it for 1 yuan! [Copy link]

1. Introduction

Some time ago, I saw a 1-yuan purchase event on the forum. The event address is [ https://bbs.eeworld.com.cn/thread-1233674-1-1.html ]. I immediately jumped on the bandwagon and received the goods within two days of the purchase.

2. Unboxing

I bought two products in total, a development board and a chip. The box they sent was very large and protected the chip very well!

There are two boxes in the box, the blue one is the development board and the white one is the chip.

The development board I chose is the EVQ4488-U-00B, a dual-channel USB charging port power converter with one input and two outputs, supporting up to 3A and is programmable.

The other white box contains a chip. The packaging is extremely good with layer upon layer of protection. There is another bag inside the white box, and another bag inside the bag. Finally, there is only one chip. If I had known the packaging was so good, I would have bought a few more chips.

The chip I bought is MP3429 21A, 16V output high-efficiency fully integrated synchronous power boost converter, which supports 30W load. The performance is still very good, and the peripheral circuit is not very complicated. You can try to design it later.

3. Summary

Things that cost one yuan are really good. The promotion should not be over yet, so hurry up!
