Hammer Technology launched the Nut QuickCharge 4+ Quick Charger in its own store when it launched the Nut R1.
There are many fast chargers currently on the market, but only the hammer is used to support QC4+ fast charging. This type of QC4+ charger for CD106 is also standard for nuts R1 phones.
To support the QC4+ protocol, the hammer uses a USB-C output connector. The official nominal output specification is 5V/3A, 9V/2A, 12V/1.5A, 3.3-5.9V/2A, 3.3-11V/2A , Maximum power 18W, but literally 11V can reach 22W, the output capacity is not bad.
As for the actual performance of this charger, today brought dismantling. In accordance with common practice, first inside and outside, take a look at this all-round charger exactly how to use materials.
One, Nut R1 Original QC4+ Charger Unpacking
Hammer R1 charger uses a simple design of the box, the front is the brand LOGO.
The graphic on the back indicates this is a charger.
Detailed parameters are marked on this surface with the model number: CD106, Output: 5V/3A, 9V/2A, 12V/1.5A.
The top 'Quick Charger' makes people at a glance.
Open the package, USB-C port external.
Remove the charger, no other standard items.
Charger simple design.
Different from the ordinary USB-A port charger, the hammer uses the USB-C port on the mobile phone charger for the first time, the domestic first.
The nominal parameters on the charger are slightly different from those on the box. There are two more PPS voltage ranges, 3.3V-5.9V/3A, 3.3-11V/2A. This time, the hammer charger leads the peers. figure.
The net weight of the charger is about 52.8g, which is a standard figure in the mobile phone charger.
The POWER-Z FL001S developed by ChargerLAB was used to detect the supported voltage level, which is exactly the same as the nominal one.
Charge iPhone8Plus, peak power up to 18W, support USB PD fast charge.
Charging for P20 PRO, power up to 15W, USB PD fast charging
Charging purple rice No. 10, power 18.5W, has exceeded the nominal 18W, indicating that there is a certain design margin.
Second, nut R1 original QC4 + charger dismantling
Violence opens the charger housing.
Remove the circuit board.
A close-up of the front, glue in place, large capacitors and transformers fixed well.
Look at the back, there is a plastic sheet between the primary and the secondary, and safety measures are in place.
First, the secondary side performs optocoupler isolation for output voltage and current feedback to meet the safety requirements of CCC certification and to prevent electromagnetic interference. SiF7N65D is a power MOS that loves semiconductors.
The 1791-02 chip is Dialog's PMW primary controller, model iW1791.
Dialog iW1791 details.
Silkscreen 9K01 UA 1810 is Dialog's latest PDW controller iW657P with built-in current detection and supports QC4+. The iW657P uses Dialog's proprietary secondary-to-primary digital communication technology. When paired with iW1781 or 1791, it only needs An optocoupler can transmit all required information to the primary side, including output voltage request, output over-current limit, output undervoltage, output overvoltage, fault and reset signals. The iW657P incorporates an optocoupler driver to reduce costs, and The D+/D-/CC1/CC2 pins are overvoltage protected and can be used to detect an overtemperature fault with an external NTC resistor. The output current sensing circuit is integrated to provide overcurrent protection for the adapter.
Dialog iW657P details.
Silk screen 603I is Dialog's synchronous rectification driver iW676; SG60N15S is Sheng Tai Microelectronics synchronous rectification tube, and iW676 form synchronous rectification. The bottom left is AO7534 MOS, used for VBUS switch.
Dialog iW676 function introduction.
It can be seen that the primary electrolysis is firmly fixed by the glue, behind the Y capacitor is the insulating plate, isolation transformer and output plate.
Independent output board, in order to prevent loosening during insertion and removal, fixed by glue, scraped off when shooting.
Dismantling summary
As the first domestic product to support the QC4+ fast charging protocol and mass production, the original QC4+ charger for nuts R1 has been a good eyeball since its release.
At present, there are already a number of mobile phones supporting the QC4+ fast charge protocol. The release of the nut charger will also be the beginning of the standard QC4+ charger for domestic mobile phones, which will help accelerate the popularization of QC4+ fast charging and USB PD fast charging.
From the perspective of dismantling, the raw materials for the original QC4+ charger for nuts R1 are also in place. The primary side uses the Dialog iW1791 as the PMW controller, and the secondary is composed of the Dialog iW676 and the Shengli Microelectronics MOS tube. The synchronous rectification scheme uses the latest Dialog. PD3.0 controller iW657P as QC4+ protocol chip.
In general, this charger Excellent performance, exquisite workmanship, materials in place.
