Wise-integration and Leadtrend introduce GaN SiP
SiP Includes Wise-integration’s 650V e-mode GaN transistor and Leadtrend’s silicon flyback controller
Wise-integration, a French pioneer in digital control of GaN and GaN ICs for power supplies, and Leadtrend Technology, a specialist in analogue and analogue-digital mixed-mode IC designs, have released a GaN system-in-package (SiP) supporting consumer electronics applications.
The collaboration’s targeted application is a 65W USB PD adapter for high-speed charging of smartphones, laptops and other devices. The LD966LGQALVE includes Leadtrend’s silicon die flyback controller and Wise-integration’s 650V e-mode 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.
The LD966L is green-mode PWMIC built-in with brown-in/out functions of a QFN8X8 package. It minimises the component count and circuit space, and reduces overall material cost for the power applications. It features HV start, green-mode power-saving operation, soft-start functions to minimise power loss and enhances system performance.
The LD966LGQALVE evaluation board features an overall peak efficiency of 93.02 percent and a power density of 22.7 W/in3.
