After the release of Apple's iPhone 13 new machine, the charging power limit of some models was raised to 27W. Due to the needs of a large number of new machine users, the 30W Mini charging market was popular. Therefore, torras tulas launched a 30W small ice charger to give consumers more choice.Charging head network learned that the reason why this charger is so small is that it adopts the gallium nitride technology called black technology, and the core scheme is to use the sc3021d + sc3503 of Nanxin semiconductor. Now let's disassemble this charger in detail to see how to design it.Previously, the charging head network has also disassembled tulas Mini 20W PD fast charging charger, tulas 65W 2c1a multi port fast charging desktop socket and other products. Welcome to consult.Turas's 30W gallium nitride Mini charger has rounded edges and corners without touching your hand. The fuselage is very small. In addition, it adopts far peak blue color matching, which is also good-looking as a whole. The charger supports pure PD3 0 fast charging protocol, with 5v3a, 9v3a, 15v2a and 20v1 5A four groups of voltage gears are not only perfectly suitable for iPhone 13 series mobile phones, but also have good compatibility with devices that support PD fast charging.Through the disassembly of the charging head network, it is learned that the charger adopts three small PCB boards welded vertically to each other, and the structure is very stable. Nanxin sc3021d + sc3503 high-frequency QR switching power supply scheme and innoseco inn650da04 second-generation gallium nitride power device are adopted. This scheme has been mass produced and applied to many big brand Mini charging products. The performance and quality have been verified by the market and unanimously recognized by customers.
