Dialog launched zero -voltage switch technology for high -power density PSU, expanding the AC/DC product portfolio

     The leading battery and power management, Wi-Fi, low-power Bluetooth (BLE), industrial edge computing solution supplier Dialog Semiconductor recently announced that it has launched an innovative digital zero voltage switch (ZVS) chipset, which can achieve 100W and above height heights above height Power density (HPD) power (PSU), size is 30%to 50%compared to traditional high -power PSUs.

     In the past, the AC/DC converter has been challenged by thermal restrictions related to equipment efficiency. Now, using Dialog's patented technology ZVS chipset, design engineers can reduce the size of the component and reduce the BOM cost, and achieve a smaller and lighter power supply, including for smartphones, tablets, laptops, electric tools and other portable portables The power adapter of the device.

     Dialog's easy -to -use ZVS RapidCharge ™ solutions include the primary side controller IW9801 and the secondary side IW709 USB PD protocol IC. Secondary digital compensation circuits can ensure stability and eliminate demand for additional compensation elements. The secondary side IW709 integrates the synchronous rectifier controller, which further reduces the number of overall components.

     This solution provides seamless multi -mode control, which can achieve an efficiency of up to 94%. It eliminates auditory noise in high -power charging. It is a small -standing charger with a small shape and a low heat -heating. It is an environmental protection with a standby power consumption of less than 20MW. solution. This chipset offers powerful functions such as overvoltage protection (OVP), overcurrent protection (OCP), user can configure over -temperature protection, common protection, input -electricity/under pressure protection, VSENSE/Isense short -circuit protection, output short circuit protection and other functions. And additional primary side overcurrent protection and overwhelmed protection.

     Davin Lee, senior vice president and advanced mixed signal business department of Dialog Semiconductor Corporation, said: "Dialog's patented ZVS technology was launched on the basis of our deep AC/DC technology expertise, and further expanded our target market to more. High -power density PSU market. This innovative ZVS chipset helps customers to easily design not only the quality of the quality, but also a high -power density charger with cost -effectiveness. "

     Dialog's ZVS chipset supports most fast charge protocols, including USB PD 3.0 supporting programming power supply (PPS) protocols and other third -party proprietary protocols. The chipset uses a maximum switching frequency of 200kHz, allowing design engineers to use smaller and lighter transformers and smaller passive devices, thereby reducing the size and weight of the charger. This complete solution adopts built -in digital compensation, making the circuit design faster and easier than the simulation solution
