Vietnam iPhone - iPad Charger Circuit Manufacturing Factory

In the iPhone – iPad charger production system, charging circuit is the “heart” of the entire device. This is where the current, voltage, charging speed are controlled and the battery is protected from the risks of overload and overheating. In recent years, Vietnam has emerged as a bright spot in the field.smart charger circuit production, with many businesses applying high technology, meeting Apple standards and international markets.

Forecast of Vietnam charging circuit market share to 2030

According to experts' predictions, by 2030, charging circuit manufacturing industry in Vietnam could account for more than 35% of the Southeast Asian supply market share. The increasing demand for electronic devices, especially smartphones, has created conditions for domestic factories to expand their scale, invest in SMT lines and fully automate the circuit testing process.

Smart charging circuit – the future of electronics

Factories in Vietnam have now switched to smart charging circuit, integrated microcontroller (MCU) capable of identifying charging devices and adjusting the appropriate current. With iPhone and iPad, the smart circuit helps optimize voltage at 5V - 9V - 12V levels, ensuring fast charging while keeping the battery absolutely safe.

High frequency switching circuit – increased charging efficiency

One of the notable improvements isHigh-Frequency Switching Circuit. This technology helps reduce power loss, improving charging efficiency by up to 95%. Factories in Vietnam are applying new generation MOSFET components, which are both compact and operate stably in the temperature range from 0°C to 70°C.

Reduce power loss with synchronous IC

UsageSynchronous ICin the charging circuit design not only helps reduce energy loss but also controls the output current precisely. Thanks to this IC, the charger can maintain a stable voltage even when the grid power fluctuates - which is especially important for the usage environment in Vietnam.

Charging circuit supports parallel charging of 2 devices

TheNew generation iPhone - iPad charging circuitIt is also designed to support charging two devices at the same time without overheating. Thanks to the automatic current regulation circuit, the voltage will be evenly distributed between the two PD and USB-A ports, ensuring that both devices charge quickly and safely.

High power mini charger circuit design

The new trend is mini charging circuits– as small as a coin but with a capacity of up to 30W. To achieve this, engineers had to optimize the layout of components, use a 4-layer insulated circuit board, and apply a layer of moisture-proof paint to protect the components when operating continuously in a high humidity environment.

Battery mode voltage regulator circuit

A highlight in MyMy Technology's smart charging circuit is the ability to adjust voltage according to each charging stage: fast charging - stable - maintenance. When the battery is almost full, the circuit will automatically reduce the current to 0.5A, helping to prolong battery life and avoid battery swelling - a common problem when using poor quality chargers.

Solution to prevent voltage fluctuations when charging

Every qualified charger must pass the test.voltage fluctuations– Simulates unstable grid conditions. The circuit is designed with high-quality filter capacitors and anti-interference inductors, ensuring that the device does not suddenly shut down or cause an electrical short circuit. This is also the reason why Vietnamese chargers are increasingly trusted in demanding markets such as Japan and Australia.

Energy-saving mini circuits – trend 2025

From 2025 onwards, factories are aiming for a tomini energy saving circuitwith 20% lower power consumption than the old model. Reducing power consumption is not only environmentally friendly but also reduces operating costs for distribution businesses.

Reduce size, increase charging circuit efficiency

This is the goal that Vietnamese engineers are pursuing –Optimize size without sacrificing performance. Each component on the board is carefully selected, ensuring high capacity, fast heat dissipation, and durable operation throughout thousands of charging cycles.
