ShenMao electronic subsoil 36 years, aluminum electrolytic capacitor
industry for aluminium electrolytic capacitor on the power supply application has the rich production experience and some application examples.
Today, we share a story about 18 w QC3 MI millet.
0 fast electrical MDY -
ED the dismantling of the article.
* note: in this paper, materials and pictures from the
Related teardown report.
Single USB - 18 w * millet
A recent electrical MDY -
A interface support QC2.
0 and QC3.
0 quick charge agreement, 18 w quick charge power can meet the demand of daily charge.
Products have passed UL certification NOM certification, Mexico and Brazil NYCE certification, mainly for overseas customers.
A, millet USB -
18 w charger port A millet the charger appearance with PC flame retardant materials white body shell, the fuselage surface of bright surface treatment technique of the lacquer that bake, side surface transition between each face, white and smooth as A whole, not restrict the hand when using.
Input shell with millet logo, and on the fuselage shell with traditional Chinese and English with the parameters of the product information model: MDY -

Transformer is placed on the other side of the middle position.
The white plastic shell, interface of the mother tongue and white at the bottom of the plastic support plate conjoined design.
A view on the back of PCB, hollow out placed between junior secondary white insulation board.
From PI SC1548C master control chip, built-in flyback type controller, the primary switch tube, and the secondary measurement detection and synchronous rectifier controller, but also with HIPOT isolation protection integration feedback link, integration is very high.
Do not need to match light coupling, when using the built-in multiple protection function.
There are a lot of businesses today that are very much in demand and one of them is a electrolytic capacitor.
