As the core component of power conversion, the ADDC chip has a wide range of application scenarios covering multiple fields, mainly focusing on the requirements of high efficiency, high integration, and high reliability. Based on the technical characteristics and industry trends, the main application scenarios and technical adaptability are summarized as follows:
1、 Industrial Automation and Semiconductor Manufacturing
Ion implantation machine power system
In semiconductor manufacturing, ion implantation machines require a low-voltage high current power supply to power the filament of the ion source unit, in order to generate high-energy electrons that bombard the gas to form ions. Traditional linear power supplies suffer from low efficiency and large size, while the use of ADDC switching power supply chips (such as TDK EMS series improvement solutions) can achieve high-frequency conversion, significantly reduce power loss, and support a wide input voltage range (such as 115V230V AC), adapting to different regional power grid standards.
Industrial Control and PLC Equipment
Industrial automation equipment, such as programmable logic controllers (PLCs), relies on high-precision power management. ADDC chips integrate PFC (power factor correction) functionality and multimodal control technology to optimize energy efficiency and meet strict electromagnetic compatibility (EMI) requirements. For example, Dongke Semiconductor's DK8715AD chip uses asymmetric half bridge (AHB) topology technology to achieve zero voltage switching (ZVS) and zero current switching (ZCS), improving system efficiency to 95.4%.
2、 Consumer Electronics and Fast Charging Technology
High power fast charging adapter
The introduction of gallium nitride (GaN) technology is driving the development of ADDC chips towards miniaturization and high power density. For example, Dongke Semiconductor's GaN encapsulated chip DK065G integrates a flyback controller and high-voltage switch tube, supporting 120W240W adapter design, significantly reducing size and improving efficiency. This type of chip is widely used in fast charging solutions for mobile phones and laptops, compatible with PD protocol and private fast charging protocol.
Home appliances and smart devices
The power module of household appliances needs to meet the Level 6 energy efficiency standard. UnionPay's U6117D chip adopts primary feedback control technology, which eliminates the need for optocouplers and TL431, simplifies circuit design and reduces costs. It is suitable for white goods such as air conditioners and refrigerators.
3、 Communication and Data Center
Optical module power management
The optical module has extremely high requirements for the stability and anti-interference of the power supply. The ADDC chip of Zhenlei Technology provides low-noise power supply for optical transceivers through high-precision control circuits and isolation design, ensuring the reliability of high-speed data transmission.
Base stations and communication equipment
5G base stations and broadband data link devices rely on efficient power solutions, and ADDC chips maintain over 90% efficiency over a wide load range through interleaved PFC and LLC resonant topologies (such as the 420W design mentioned in webpage 3), adapting to complex power grid environments.
4、 New Energy and Automotive Electronics
Electric vehicle charging system
Car chargers (OBC) and two wheeled electric vehicle chargers need to balance high power and safety. ADDC chips integrated with gallium nitride devices (such as DK8715AD) improve charging efficiency and extend battery life through multiple protection mechanisms (overvoltage, overcurrent, overtemperature) and adaptive load modes.
Solar inverter
In photovoltaic systems, ADDC chips are used for power management of MPPT (Maximum Power Point Tracking) modules, adapting to outdoor environmental fluctuations through a wide input voltage range (such as 2.0V5.5V) and temperature compensation function (such as MDC02 chip).
5、 Medical and Precision Instruments
Medical equipment power supply
Medical devices, such as monitors and imaging equipment, are sensitive to power ripple and noise. The ADDC chip utilizes LC filtering and isolated DCDC design (as discussed on webpage 10) to separate digital and analog power sources, reduce interference, and ensure signal acquisition accuracy.
Laboratory instruments
High precision ADC chips (such as TI's ADS8688 series) rely on low-noise power supplies, while ADDC chips support a wide input range of ± 10.24V by integrating reference voltage buffers and multiplexers, meeting precision measurement requirements.
Technological Trends and Challenges
High frequency and integration: The switching frequency is increased to 800kHz (such as DK8715AD), combined with encapsulation technology (controller+driver+GaN device), further reducing the size.
Intelligent control: Supports digital single bus interfaces (such as MDC02 chip) to achieve multi node distributed sensing and remote configuration.
Energy efficiency and reliability: The Level 6 energy efficiency standard promotes chip optimization of standby power consumption (<50mW), and enhances system robustness through RCD absorption circuits, over temperature protection, and other measures.
In summary, the ADDC chip continues to expand its application boundaries through technological innovation, from traditional industries to emerging intelligent IoT. Its core value lies in balancing efficiency, volume, and cost to meet the power management needs of diverse scenarios.
