WDA Pinjia Group launched a 140W power adapter solution based on Infineon products

 


【Lansheng Technology Information】On September 7, 2023, Wanda Holdings announced that its subsidiary Pinjia launched a 140W power adapter solution based on the Infineon XDPS2221 chip.


Since the introduction of the USB PD3.1 specification, the market capacity of PD chargers has greatly increased. The specification adds three extended output voltages of 28V, 36V, and 48V, and increases the maximum output power from 100W to 240W. This means that USB PD chargers that are originally suitable for electronic products such as mobile phones and tablets can also be used in power tools or two-wheeled electric vehicles. In order to accelerate the popularization of the USB PD3.1 specification, Dalian Dapinjia launched a 140W power adapter solution based on the Infineon XDPS2221 chip, which can help manufacturers accelerate the design and development of related products.


XDPS2221 is an adaptive PFC and soft-switching HFB combo controller with three built-in gate drivers. The internal integrated coreless transformer drive has high withstand voltage and strong anti-interference ability, which can significantly improve the reliability of the product. At the same time, the drive current and current slope can be adjusted to facilitate the optimization of EMI characteristics. Not only that, the adaptive PFC output and dynamic start-stop function of the chip can work with the post-stage HFB to maximize the average and light-load efficiency.


At the same time, XDPS2221 has the characteristics of zero-voltage switching (ZVS), and it can be used together with Infineon's GaN MOSFET switch products to achieve the purpose of optimal design. Moreover, the high-frequency operation of the device can further reduce the size and volume of the magnetic parts, thereby easily helping customers realize products with high power density.


Due to the high integration characteristics of this solution, the number of peripheral components can be greatly reduced, and the production cost can be further reduced. Not only that, the Hybrid Flyback architecture supports a wide output voltage, which can meet the needs of various product applications. Through this solution, it will help manufacturers create more competitive USB PD3.1 high-power charging products and quickly seize market share.

What are the Benefits of Power Optimizers?

Image
  Power optimizer for solar panels is a DC/DC converter that is connected to each solar panel in the PV system, turning them into smart modules. By constantly monitoring the maximum production capacity of each individual solar module, optimizers can increase your PV plant energy production – potentially increasing revenue and shortening system payback time. Simply put, the main benefit of power optimizer is that it maximizes the performance of each panel individually. What are the benefits of power optimizers and why are they needed? When installing solar panels, the panels are connected into groups or arrays. In the case of roof-mounted and in-roof panels, there are usually 12-20 solar panels in one group. If the productivity of one of these panels decreases (shadows from trees and clouds, dust, bird droppings, failures of PV components and other factors), then the productivity of the whole group decreases. Defective or shaded panels may produce 15 to 25 percent less solar energy ...

What is a Power Conditioner?

Image
  Looking to protect your sensitive and expensive electronics? Surge protection is a great start, but power conditioners also offer valuable protection for components in entertainment and sound systems, as well as home office devices. What does a power conditioner do that a surge protector can’t? Surge protectors are a great defense against damaging voltage spikes. However more than surges and spikes can effect certain sensitive electronic devices. Radio frequency interference (RFI), electro-magnetic interference (EMI) and voltage fluctuations can also effect sound, entertainment, and office devices, causing a reduction in sound and picture quality. How does it work? Power conditioners act as a buffer between the outlet and your system, smoothing out voltage fluctuations as well as radio and electromagnetic interference that can effect system performance. Initially used in industrial, research and laboratory applications, not long after the introduction of home computer systems, th...
