When legitimate authority focuses attention on charger of malic 18W USB PD, the apple is however after congress of WWDC 2018 developer go up sadly wore charger of a 30W USB PD. Meanwhile, original 29W USB PD also is fallen to wear, that is to say this 30W charger replaced original 29W charger.
Comparative discovery, these two charger differ besides model, parameter and crust workmanship besides, product function also has very big difference, the compatibility that waits to mobile phone, mobile power source for instance, the output voltage when charging to new fund MacBook somewhat difference.
Undertake a detailed contrast to the interior of these two charger today, make everybody right the waits for a respect with makings, charge for the making of sth. difference of these two charger has a more clear knowledge.
Left is new fund 30W, right is old money 29W. Both dimension size agrees completely, only appreciably distinguishs the appearance. Main distinction depends on: Archives of outlet of crust, interface, AC, voltage wait. The crust of right 29W is an organic whole, and adapter of 30W of left new fund is by two solder together partly. In addition, USB-C interface also has appreciably distinction.
The model of 0W is A1882, output norms parameter is 5V3A, 9V3A, 15V2A, 20V1.5A; And the model of 29W is A1540, output norms parameter is 5.2V2.4A, 14.5V2.0A, only 2 archives. Above is this two paragraph charger basically distinguish in apparent, the interior that sees two charger next uses makings and do manual work.
One, charger of malic 30W USB PD tears open solution
Force tears open above carapace.
Accumulate Fu copper in the round, increase medicinal powder hot, crust interior hits glue to help heat conduction. This kind comes loose hot configuration is only commonly on high-power jotter power source see.
Live wire, 0 lines, ground wire.
Screw of Torx of ground wire interior is fixed.
Black insulating tape.
Sheet copper is whole those who encase.
Tear apart shrink canal, close-up of lead solder contact, cross starting a hole, solder firm.
Sheet copper is whole take out.
In-house circuit uses two PCB design, use plastic outer covering to secure, primary circuit board above the lid has plastic cover, insulation supports action.
Sub commutate outputs circuit.
USB-C exports plug-in unit, two capacitance paralell connection is in charge of outputting filter wave.
Live wire inserts a foot to use shrink assure to protect, be isolated from a card opening slot the foot is brought to go up in fuse, and hit glue secure.
Two electrical wiring also are to use the insulating part of sizy and fixed interiorly here, craft fastidious.
Depart drops the insulation among two circuit board to keep apart a cover.
Capacitance of ruby of two 35V 33μF and a day change KXJ to electroanalysis capacitance, compression 400V 39μF, of intermediate end up is Y capacitance, also have an insulating part likewise.
This angle can see an input in all modular inductance, fuse, pressure quick resistor.
The wave of filter of 400V 39μF input of series of Japanese Hei Jingang KXJ electroanalysises capacitance, transformer is Sheng Meida acting labour.
Fuse, capacitance a side still has a join that discharge a line to arrive output circuit board to go up, the look is much more inside than traditional charger a filmy capacitance, meet below respecting.
Y capacitance close-up.
Circuit board is rear, this power source and we common power source framework is abhorrent, it is ACF active clamp structure.
FLUT12A2060 is Infineon Ying Feiling is primary advocate accuse IC, custom-built model, use PG-DSO-12 to enclose. As a result of LLC framework, form a complete set has the switch of two Ying Feiling to be in charge of.
IPL65R1K5C6S of Infineon Ying Feiling is detailed data.
IPL65R650C6S, all belong to series of Ying Feiling CoolMOS C6. Clamp of active of ACF of two pipe composition framework, improve efficiency. The MOSFET that ThinPAK encloses, ply has 1mm only, enclose than common TO220/252, reduce volume greatly, can increase the power density of adapter, special the design that applies to small-sized adapter.
USB-C platelet front, can see additionally one board platoon line is join to smooth Ou.
Continue to look there still is element among capacitance.
Install controller of dark beauty synchronous commutate, this model is not had inside product list, belong to custom-built model.
FDMS86201 synchronism commutate is in charge of Ansenmei, see PCB is turmeric here. 120V compression, 49A, 11.5mΩ .
An Sen beautiful FDMS86201 is detailed data.
USB-C platelet the reverse side is Saipulasi chip of USB PD agreement.
Saipulasi consultative chip close-up, silk imprints the CCG3 of chip of USB PD agreement that is Saipulasi for CYPD3135.
CCG3 is the USB-C with a kind of compositive height controller, accord with newest USB-C and PD standard, had obtained USB PD2.0 attestation at present. CCG3 is solution of a complete USB-C and control of port of USB power source, can use at notebook computer, show inspect implement, extend the equipment such as a depressed place and power source adapter. CCG3 uses technology of Cypress proprietary M0S8, have 32, processor of 48-MHz ARM Cortex-M0, have 128 KB to shine put, 8KB SRAM, 20GPIOS, amain USB device control character implement. Can use at adjuster of fault tolerance of the password engine of attestation, 20V, and 5V of switch of a pair of FET (VCON) power source, for cable power supply. CCG3 is compositive still driver of two pairs of grid will control exterior VBUS FET and protection of systematic level ESD, in application of power source domain, CGG3 is commonly used of 40-QFN, 32-QFN two kinds enclose a form.
1014-418 is a smooth Ou, be in charge of and PWM controller communication, adjust output voltage and shed protection too, right next horn are VBUS switch canal and voltaic sampling resistor.
Charger interior uses installation of 6 insulation mould, this also is unprecedented on charger.
Charger is all circuit is rear.
Rectification bridge hides in in all below modular inductance.
The inductance of capacitance a side.
This angle can see electroanalysis capacitance is sizy and fixed, prevent to become loose.
Transformer assists winding to output rectification.
Tear open solution thing general view entirely.
