Wise-integration & Leadtrend Technology Introduce GaN System-in-Package Targeting Rapid Consumer Device Charging

Wise-integration, a French pioneer in digital control of gallium nitride (GaN) and GaN ICs for power supplies, and Leadtrend Technology Corporation (TWSE stock code: 3588), a specialist in analog and analog-digital mixed-mode IC designs, today announced the release of a GaN system-in-package (SiP) supporting consumer electronics applications.

Their collaboration’s targeted application is a 65-watt USB PD adapter for high-speed charging of smartphones, laptops and other devices. The LD966LGQALVE High Voltage Multi-Mode PWM Controller of Flyback with GaN integrated includes Leadtrend’s silicon die flyback controller and Wise-integration’s 650V e-mode gallium-nitride (GaN) transistor die in a SiP. The SiP has passed 1,000 hours of operating life tests (OLT).

“This SiP enables original design manufacturers (ODM) to develop a less expensive system with fewer components, a smaller printed circuit board and faster system-development time,” said Thierry Bouchet, CEO of Wise-integration. “This collaboration also underscores Leadtrend’s confidence in the breadth and depth of our GaN expertise and the quality of our products.”

The LD966L is green-mode PWMIC built-in with brown-in/out functions of a QFN8X8 package. It minimizes the component count, circuit space, and reduces overall material cost for the power applications. It features HV start, green-mode power-saving operation, soft-start functions to minimize power loss and enhance system performance.

The LD966LGQALVE Evaluation Board features an overall peak efficiency of 93.02% and a power density of 22.7 W/in3.  More information https://www.leadtrend.com.tw/tw/product-page/12/355-ld966L.

Wise-integration has optimized GaN capabilities to make power-electronics technology both greener and more efficient with high-current, high-voltage breakdown and high switching frequency. Its WiseGan® power-integrated circuit (IC) combines several power electronics functions into a single GaN chip for improved speed, efficiency, reliability and cost-effectiveness.

The company opened an office in Taiwan in 2022, and uses 650V GaN/Si technology from Taiwan Semiconductor Manufacturing Co. (TSMC) in its  650V e-mode GaN transistor die with ESD protection.

Wise-integration recently announced the closing of its Series B round of funding totalling 15 million.
