“The current power supply products are developing in the direction of thinness and compactness. However, the reduction in volume means the improvement of product integration and the reduction of heat dissipation area. For this problem, some manufacturers choose to use gallium nitride power devices to replace traditional silicon MOS, in order to achieve the purpose of reducing the volume and reducing heat dissipation while improving the power conversion rate.

The current power supply products are developing in the direction of thinness and compactness. However, the reduction in volume means the improvement of product integration and the reduction of heat dissipation area. For this problem, some manufacturers choose to use gallium nitride power devices to replace traditional silicon MOS, in order to achieve the purpose of reducing the volume and reducing heat dissipation while improving the power conversion rate. However, although the high-frequency and high-efficiency advantages of GaN power devices make up for the loss caused by reducing switching, the loss of the traditional input-side rectifier bridge is unchanged, and as the output power increases, the power consumption of the rectifier bridge will also Synchronized rise. In order to solve this problem, Dalian Daquan Ding has launched a high-efficiency active bridge rectifier power supply solution based on the AOS AOZ7200CI chip, which can effectively reduce the loss of the rectifier circuit and improve the power conversion efficiency.

AOS (Bandai Semiconductor) is a power semiconductor device supplier integrating design, development, production and global sales. The company is committed to helping customers cope with the increasingly complex power requirements of advanced Electronic products through continuous innovation of technologies, products and solutions. The core of this solution is the AOZ7200CI chip using AOS, which is a high-efficiency bridge rectifier control IC that can replace the diodes in traditional bridge rectifiers, thereby improving efficiency and reducing heat sources. Compared with other similar products on the market, AOZ7200CI has higher efficiency, especially in light load mode, the unique control method of the device can effectively reduce light load losses.

This solution provides the easiest way to reduce power loss. With the help of the solution, the miniaturization of power products can be further realized. After testing, under the same power, this solution can not only provide excellent heat dissipation capacity, but also reduce the product volume by 30~40%.
Core technical advantages:
• Low working current (12uA), good performance in no-load loss;
• No negative current during shutdown;
• Good loss performance at high voltage and no load;
• Good EMI performance;
• Very few peripheral components, simple and stable application.
Program Specifications:
• Input voltage: 90Vac ~ 264Vac;
• Output power: 280W;
• MOSFET: 600V/125m ohm;
• No-load loss: <[email protected]
