Vietnam iPhone - iPad Charger Circuit Manufacturing Factory
In today's mobile device ecosystem, the charger circuit is the “heart” that determines the safety, performance and lifespan of the device. An international standard charging circuit not only transmits electricity stably, but also controls temperature, cuts off overload and reduces energy consumption.
In Vietnam, MyMy Technology to be iPhone - iPad charger circuit manufacturing workshopLeading, specializing in designing and manufacturing high-power circuit boards, meeting USB Power Delivery standards (PD 3.0, PD 3.1), trusted by domestic and foreign enterprises.
5V–20V output power control circuit
The difference in MyMy Technology products is5V–20V flexible power control circuit, compatible with many devices from iPhone, iPad to MacBook.
The circuit usedSmart PWM pulse converter IC, allow automatic output voltage regulation according to the device's requirements. When charging an iPhone, the circuit drops to 5V; when charging an iPad or MacBook, the circuit automatically increases to 9V, 15V, or 20V depending on the PD standard.
This technology helpsOptimize charging speed, reducing energy loss, whileprevent overcurrent and overheating, protecting both the charger and the device battery.
Voltage feedback system in MyMy Technology charger
An important point of modern charging circuit is feedback circuit.
At MyMy, this system is designed based on opto-coupler and Precision voltage sensor IC, to help maintain stable output voltage even when load changes continuously.
The continuous feedback mechanism allows the charger to detect when the voltage drops and automatically adjust the power to maintain stability.
Thanks to that, MyMy Technology circuit can operate stably for many hours withoutOutput voltage that does not fluctuate more than ±3%, ensuring absolute safety for iPhone, iPad and other power-sensitive devices.
Anti-leakage design in charging circuit
One of the criteria that MyMy especially focuses on is absolute electrical safety.
The charger circuit products here are all double insulation design, combine PCB moisture-proof coating and ARC Resin anti-conductive material.
Each board is tested for electrical leakage according to international standards, ensuringLeakage current less than 0.25mA, far exceeding CE and UL safety regulations.
Besides, Input and output filter capacitors are arranged in isolation.to avoid electrostatic discharge (ESD), and to minimize the “shock” phenomenon when users charge for a long time.
Thanks to that,MyMy charger always works safely, durably and is user-friendly..
Analysis of 1C, 2C and 3C charging circuit structure
Depending on the purpose of use, MyMy Technology produces many product lines.different charger circuit, include:
- 1C circuit (1 USB-C port): for small capacity charger 20W–30W, suitable for iPhone, iPad mini.
- 2C circuit (2 PD ports): supports charging two devices simultaneously, smart load sharing capacity 45W + 18W.
- 3C circuit (3 charging ports): built-in power distribution algorithm, helps three devices charge quickly without overheating.
These circuits all use Gan Fast central control ICNew generation, providing conversion efficiency up to95%, helping to save energy and prolong component life.
Multilayer PCB for fast charging
To meet the high power fast charging requirements, MyMy appliesMultilayer Board (Multilayer Board) technology with 4–6 parallel copper layers, help:
- Reduce the impedance of the power line
- 30% faster heat dissipation
- Increased stability when operating at high capacity
Each circuit layer is insulated with flame retardant FR-5 material and heat-pressed using technology.vacuum lamination, ensuring a thin - compact - durable circuit but still maintaining high performance.
As a result,The product is 20% more compact than the conventional silicon generation., But stable power transmission and less heatwhen fast charging.
Standard PCB size in iPhone charger
Depending on the power line, PCB size is optimized by MyMy Technology as follows:
- PCB 22×25mm: 5W – 18W charging (iPhone SE, iPhone 11)
- PCB 28×32mm: sạc 20W – 30W (iPhone 13–15 Series)
- PCB 35×40mm: 65W – 100W charging (iPad, MacBook Air)
Standardization of sizes helps easy to assemble and test, while reducing component costs for OEM/ODM partners.
