HUA XUAN YANG ELECTRONIC Provides A Power Device Solution Tailored for In Car Wireless Mobile Phone Chargers
In the era of intelligent cars, convenient and efficient in car devices have become a key element in improving driving experience. Among them, in car wireless mobile phone chargers are loved by car owners due to their unrestricted and on-demand charging characteristics. However, behind an excellent wireless charger, precise matching, efficient and stable power device support is indispensable. Today, I will take you to deeply understand the power device solution tailored for in car wireless mobile phone chargers (with three built-in coils), including MOS tubes, transistors, and LDO, allowing the power of technology to quietly inject infinite convenience into your driving life.
1. MOS transistor: the core power driving wireless chargingIn wireless chargers, MOSFETs, as power switching components, play an important role in current switching and voltage control. We recommend using MOSFETs with the following characteristics:
Efficient conversion: This model of MOSFET has ultra-low on resistance (Rds(on)), effectively reducing power loss, improving overall system energy efficiency, and ensuring fast and stable wireless charging process.
Excellent thermal stability: With excellent thermal resistance characteristics, it can maintain good working condition even under high temperature conditions in the vehicle environment, extending the service life of the device.
Quick response capability: With short switching time and low gate charge, it ensures fast response to changes in charging state, providing precise control for multi coil charging.
2. triode: Precise regulation to ensure stable chargingThe transistor plays the role of voltage amplification and current driving in wireless chargers, used to achieve precise control during the charging process. The transistor we recommend has the following advantages:
High gain characteristic: With a high current amplification coefficient, it can effectively amplify weak control signals, ensuring precise adjustment of charging current
Wide working voltage range: Adapt to voltage fluctuations in the onboard power supply, ensuring stable operation under various working conditions, and avoiding charging interruptions or abnormalities caused by voltage fluctuations.
Good temperature stability: Equipped with a built-in temperature compensation mechanism, the wireless charger has stable performance within the working temperature range, ensuring long-term reliable operation in complex vehicle environments.
3. LDO: Pure Power Supply, Safeguarding Battery Health. LDO (Low Voltage Differential Linear Stabilizer) is responsible for providing pure and stable power to the control circuit of wireless charging systems, which is crucial for protecting mobile phone batteries. The LDO we provide has the following characteristics:
Ultra low noise: Built in high PSRR (power suppression ratio) design, effectively filtering out power noise, providing "clean" power for control circuits, improving charging accuracy and phone battery life.
Fast transient response: In case of sudden load changes, the output voltage can be quickly adjusted to prevent voltage drop or overshoot, ensuring a smooth and undisturbed wireless charging process.
Low temperature rise and low power consumption: Adopting an efficient architecture design, the temperature rise during operation is small, and the power consumption is low, which meets the energy-saving and environmental protection requirements of on-board equipment.
HUA XUAN YANG ELECTRONIC power device solution for car mounted wireless mobile phone chargers integrates efficient driving of MOS transistors, precise regulation of transistors, and pure power supply of LDO, optimizing charging performance in all aspects, providing car owners with a safe, fast, and worry free wireless charging experience.
