It is not new for the same type of charger to be produced by different foundries, especially for large mobile phone brands, such as today's millet 6 original charger MDY-08-ES.
Friends who care about this brand should all know it. Millet mobile phone chargers are generally produced by BYD, Chenyang, Olympia, and other foundries. However, because of the charger's appearance, model, and performance are not too different, so few people care about their differences.
However, for the appearance, model, and performance of the two chargers, which have almost the same performance, there is no difference in the internal materials and workmanship.
This article dismantled the millet 6 original charger MDY-08-ES BYD version and Chen Yang version. Product material in the end is better or worse? Look at the details later in the article.
The two chargers are only slightly different in the identification of the parameters, but this is only different from the font style and the foundry. The location of the various logos is almost the same. If you do not look closely, it is difficult to distinguish from the appearance.
One, millet MDY-08-ES BYD dismantling
Internal PCB version of the main view, you can see, the front of the charger is easily damaged by the vibration of the components are all fixed with insulating adhesive, but also to enhance the heat dissipation. And in the input are equipped with fuses, NTC as input protection.
In terms of capacitance, the BYD version input capacitance comes from AiSHi, with a primary filter of 18μF+12μF for a total of 30μF.
The output uses two 16V 330μF solid-state filter capacitors, the brand is unknown.
In terms of chips, BYD version of the primary PWM controller Dialog's iW1782.
Dialog iW1782 with its own QC3.0 recognition IC, can form a highly efficient, powerful QC3.0 power adapter.This chip is widely used, including the hammer CD101, Jin TC-G800, Le EQ-24BCN, Mito MA- 1607 other mobile phone original charger.
BYD version of the recognition IC, screen printing 6A0V, the same brand and power master, provided by Dialog.
For MOS tube, BYD version uses core technology synchronous rectification MOS, model SW088R6VT.
Core send technology SW088R6VT, pressure 60V, resistance 11 milliohms.
At the same time using the core technology to send SW7N65 primary primary switch.
