French-based company Wise-integration, together with Leadtrend Technology Corporation, a specialist in analogue and analogue-digital mixed-mode IC designs, has announced the release of a GaN system-in-package (SiP) for consumer electronics applications.

This collaboration focuses on a 65-watt USB PD adapter designed for high-speed charging of smartphones, laptops, and other devices. The LD966LGQALVE High Voltage Multi-Mode PWM Controller with GaN integration includes Leadtrend’s silicon die flyback controller and Wise-integration’s 650V e-mode gallium-nitride (GaN) transistor die in a single SiP, which has successfully passed 1000 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 a green-mode PWMIC with built-in brown-in/out functions in a QFN8X8 package. It reduces the component count and circuit space, thus lowering overall material costs for power applications. It features HV start, green-mode power-saving operation, and soft-start functions to minimise power loss and enhance system performance.

The LD966LGQALVE Evaluation Board boasts an overall peak efficiency of 93.02 percent and a power density of 22.7 W/in³.

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

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

Wise-integration recently completed its Series B funding round, raising a total of €15 million.
