Transphorm and Weltrend release more GaN SiPs
SuperGaN-based SiP family now expands power level support
GaN company Transphorm and Weltrend Semiconductor have announced two new GaN System-in-Packages (SiPs), for use in high-performance, low-profile USB-C power adapters for devices such as smartphones, tablets, laptops, headphones, drones, speakers, cameras, and more.
When combined with Weltrend’s flagship GaN SiP announced last year, the new devices establish the first SiP product family based on Transphorm’s SuperGaN platform.
The new SiPs—WT7162RHUG24B and WT7162RHUG24C—integrate Weltrend’s high frequency multi-mode (QR/Valley Switching) Flyback PWM controller with Transphorm's 150 mΩ and 480 mΩ SuperGaN FETs respectively. Like their 240 mΩ predecessor (WT7162RHUG24A, pictured above), the devices pair with USB PD or programmable power adapter controllers to provide a total adapter solution.
Notably, they also offer several innovative features including the UHV valley tracking charge mode, adaptive OCP compensation, and adaptive green mode control among others that allow customers to design high quality power supplies faster and with fewer components using the simplest design approach.
“When we launched our first GaN SiP last year, it was an important milestone in our company’s evolution. It demonstrated a new GTM strategy for the AC-to-DC power market,” said Wayne Lo, VP of marketing, Weltrend. “Today’s news confirms we’re continuing to serve that space with a wider selection of devices designed to support a wider assortment of product power levels. A total packaged solution with Transphorm’s SuperGaN platform delivers design simplicity with unparalleled performance for devices now ranging from low 30-watt USB-C PD power adapters through to nearly 200-watt chargers, a unique Transphorm GaN capability.”
“SiPs are an important device option when considering the needs of adapter and charger manufacturers,” said Tushar Dhayagude, VP of Worldwide sales and FAE, Transphorm. “These systems require effective power conversion that, while simple to use with integrated functionality, also minimise learning curves to ensure quick design in. The first device released validated the performance and versatility of a SuperGaN SiP. The new devices announced today validate both our companies’ deepening commitment to arming customers with choice.”
