December 28, 2023 - Transpharm, Inc. (Nasdaq: TGAN), the world's leading GaN power semiconductor supplier, and Weltrand Semiconductor Inc. (Weiquan Electronics, TWSE: 2436), the world leader in integrated circuits for adapter USB-C PD controllers, announced the joint launch of the 100W USB-C PD power adapter reference design. The reference design circuit adopts the system level packaging (SiP) SuperGaN jointly developed by the two companies ® Power control chip WT7162RHUG24A The efficiency of 92.2% can be achieved in the quasi resonant flyback (QRF) topology.
This reference design is the second one launched by Weiquan Electronics WT7162RHUG24A QRF topology USB-C PD adapter control board. Earlier this year, Weiquan Electronics released a 65 watt adapter control circuit. The two adapter control boards use the same SuperGaN SiP. Compared with the competitive solution, customers can realize the 100 watt product design at a higher cost, thus achieving economies of scale. This also shows that the 65 watt power level SuperGaN SiP also meets the performance and cooling requirements of the 100 watt power level design.
Philip Zuk, senior vice president of business development and marketing of Transpharm, said: "The idea that GaN based integrated circuits can simplify the design is great, but it must be" integrated ". It must be a single integrated device that encapsulates the necessary controller. This is the advantage of the SuperGaN SiP of Weiquan Electronics and Transporm. Our system level packaging is a simple normally closed solution, without the need to protect circuits, drives or external controllers. In addition, the same SiP is also suitable for 65W and 100W power adapters. The products and solutions with these highlights truly demonstrate the comprehensive performance advantages and robust characteristics inherent in GaN. At present, only Transpharm's SuperGaN platform can achieve this. "
Wayne Lo, Vice President of Marketing of Weiquan Electronics, pointed out that "Weiquan Electronics' market share in the AC-DC power supply market is growing, and it is most important for us to ensure that we can provide the best and most practical solutions for the market. At present, taking advantage of many attractive performance advantages of GaN materials, the power adapter market is constantly innovating and iterating. What Weiquan Electronics needs to do is to ensure that customers can benefit from these advantages of GaN - not only in technology, but also in a better and more comprehensive return on investment (ROI). One SiP not only meets the physical design requirements of the adapter, but also applies to different models of the entire adapter series. This is a win-win situation for Weiquan Electronics, Transporm and customers. This newly released 100 watt reference design scheme strongly proves that our technology is also competitive in the low price market, but this is just the beginning and the future is foreseeable. "
100 Watt Adapter Reference Design Specification
The universal 100W power adapter verification board of Weiquan Electronics is designed according to the USB PD 3.0+PPS standard, which is used to quickly develop various flat high-performance power adapters for charging smart phones, tablets, laptops and other smart devices. The main technical specifications are as follows:
SuperGaN SiP: compact structure, high cost efficiency, accelerating product development
WT7162RHUG24A It is a true integrated circuit designed for use with USB-C PD power adapters from 45 to 100 watts. This device integrates Weltrend's WT7162RHSG08 Quasi resonant/multi-mode flyback PWM controller and 240 milliohm, 650 V SuperGaN of Transporm ® FET。 The SiP IC is a 24 pin 8x8 QFN packaged surface mount device, which can achieve a peak efficiency of 92.2%. The main advantages include higher power density and better heat dissipation performance. Therefore, it has longer term reliability and reduces BOM material cost.
