Transphorm, Inc. (Nasdaq: TGAN)—a pioneer in and a global supplier of high reliability, high performance gallium nitride (GaN) power conversion products—and Weltrend Semiconductor Inc. (TWSE: 2436), the global leader in adapter USB Power Delivery (PD) Controller Integrated Circuits (ICs), today announced the release of their first GaN System-in-Package (SiP).

The WT7162RHUG24A is an integrated circuit designed for use in 45 to 100 watt USB-C PD power adapters charging smartphones, tablets, laptops, and other smart devices. It offers peak power efficiency of greater than 93%. Device samples will be available in the second quarter of 2023.

In addition to bringing a new product to market, this announcement marks another major achievement by Weltrend. This new GaN SiP now shows Weltrend’s commitment to the AC-to-DC power market as they offer a complete system solution using Transphorm’s SuperGaN® technology. For Transphorm, it is another key proof point that validates its GaN devices’ ease of interface and superior performance.

Transphorm will showcase the Weltrend SiP for the first time at the 2023 Applied Power Electronics Conference (APEC) in booth #853. The companies will also release details on the related WTDB_008 65W USB PD Power Adapter Evaluation Board during the event.

“The WT7162RHUG24A is the industry’s first publicly announced SiP using Transphorm GaN. It enables manufacturers to develop a less expensive system solution given fewer components are required and a smaller PCB can be used among other advantages. It also reduces system development time. Effectively, we’re removing design barriers for adapter manufacturers,” said Tony Lin, President, Weltrend. “Notably, this product also allows Weltrend to move into a new market. It is the first-ever SiP for our PWM controllers, validating our commitment to supporting high volume growth sectors. And, with the integration of the GaN FET, we’ve raised the level of performance output. A win for Weltrend, Transphorm, and our mutual customers.”

“The adapter fast charger market is a fast growing segment for GaN adoption today. We are gaining market share and continue to innovate, most recently with this GaN SiP, which allows for even easier use of our GaN devices,” said Primit Parikh, President and COO, Transphorm. “We’re excited to integrate our industry leading SuperGaN platform with Weltrend’s innovative adapter power controller technology. Weltrend has delivered a leading power conversion platform which creates a simple-to-use solution for adapter/fast charger customers that both companies can use to accelerate wins in this market.”

WT7162RHUG24A Specifications and Features

The new SiP integrates Weltrend’s WT7162RHSG08 multi-mode flyback PWM controller with Transphorm’s 240 milliohm, 650 volt SuperGaN® FET. The surface mount device is available in a 24-pin 8x8 QFN package, reducing PCB size. Other key specifications include:

Adjustable turn on/off speed of GaN FET

Increases flexibility of EMI testing and solution operation

External VDD linear regulator circuit not required

Reduced package parasitics (inductance, resistance, capacitance)

700V ultra HV Start-up Current pulled directly from Line/Neutral of AC main voltage

Fits in 8x8 QFN package despite PWM chip addition

Allows for low profile/small system footprint

The WT7162RHUG24A SiP is optimized for use in high-performance, low-profile USB-C power adapters for mobile/IoT devices such as smartphones, tablets, laptops, headphones, drones, speakers, cameras, and more.
