[MPS Mall Mini Program Online Huge Discount] Unboxing, Synchronous Buck Converter with i2c Interface? [Copy link]

Recently I received an invitation from eeworld to place an order through its mini program and get a cashback.

Without hesitation, I ordered an MP8864 verification board to learn from it.

A few days later, I received a huge box

(It is a bit big, enough to install a host)

Unboxing!

When I opened the box, the first thing that popped out was a promotional leaflet for the inductor

As we all know, MPS is famous for its excellent power modules, and its inductors are also very useful products in the industry.

It's a bit of a waste to put only these few boxes in such a big box.

Main part--The packaging of this ev8864 is still very beautiful

clang clang !

This is the protagonist of this article: the EV8864-Q-00A high-efficiency synchronous buck converter verification board

As you can see, the workmanship is still very exquisite.

The entire board is designed in full accordance with the layer recommendations in the MP8864 chip manual, which can facilitate layout engineers to make a more complete reference when using the MP8864 chip.

The chip in the center is the heart of the board: the mp8864 synchronous buck converter

The MP8864 is special in that it has an I2C interface for programmable output (ranging from 0.6V to 1.87V in 10mV steps). The voltage change slope, switching frequency and power saving mode can also be selected through the I2C interface.

I will post the specific data below

In addition, the side dishes this time are a 5V power charging IC of mp2664 and three 1.0uh semi-shielded inductors of model MPL-SE2512.

Because it is a more commonly used model, I will not go into details here.

As for why I bought an inductor when I exceeded the order limit... My personal reason was that when I was watching Mr. Wen's DCDC tutorial, I was very interested in MPS's inductors, so I bought one and happened to use it as an inductor for my next project (I would like to thank Mr. Wen Tianxiang here)

In short, the adjustability of this chip is much stronger than that of traditional buck converters. I will also publish some usage experience and related applications of MP8864 chips when I have the chance. Please stay tuned.

At the same time, I would like to thank EEWORLD for providing me with this valuable experience opportunity, which allows me to explore the mysteries of the electronic world with you masters.

It seems that the MPS inductor I bought by the way is also very powerful

Programmable is a trend
