Transphorm and Weltrend Semiconductor Release New Integrated GaN System-in-Packages
SuperGaN-based SiP Family Now Includes Three Devices, Expanding Power Level Support for a
The new SiPs—WT7162RHUG24B and WT7162RHUG24C—integrate Weltrend’s high frequency multi-mode (QR/Valley Switching) Flyback PWM controller with
“When we launched our first
End product manufacturers seek ways to develop new adapters with a reduced bill-of-materials (BOM) that offer versatility, fast charging, and higher power outputs. Additionally, in many cases they seek to deliver “one-size-fits-all” chargers with multiple ports and/or multiple types of connections. All of this in smaller, lighter weight form factor.
Some key advantages of Transphorm’s normally-off d-mode SuperGaN platform include best-in-class robustness (+/- 20 V gate margin with a 4 V noise immunity) and reliability (< 0.05 FIT) with the ability to increase power density by 50% over silicon. Weltrend’s elegant SiP designs harness those advantages along with its own innovative technologies to create a near plug-and-play solution that speeds design while reducing form factor size.
“SiPs are an important device option when considering the needs of adapter and charger manufacturers,” said
