The "SiC-in-Package" era has arrived, with five major domestic manufacturers—BPS, Chipown, iSmartWare, Meraki, and Silicon Power—leading the integration of PWM controllers, drivers, and SiC power devices into single chips. This design minimizes PCB footprint, suppresses EMI, and optimizes efficiency for 18W–140W power supplies, making high-performance third-gen semiconductors more accessible than ever for fast chargers and industrial power applications.
Manufacturers have built a versatile matrix of hardware options to suit different power tiers and thermal needs. BPS focuses on high-power performance with its 800V-rated BP83323 for 140W systems, while Chipown provides flexible solutions from 18W to 110W for networking and power adapters. iSmartWare’s 130kHz SW series targets the 50W–100W PD market, Meraki offers differentiated 65W "gemini" options with varying resistance, and SiC power’s SP947X series leverages intelligent multi-mode switching to cover the 36W–100W range with optimized heat dissipation.
These integrated chips eliminate the engineering hurdles—like parasitic inductance and EMI—that previously hampered discrete SiC power designs. As the industry moves toward the 2026 World SiC Conference on June 12th, adopting this integrated, multi-mode architecture offers a clear competitive path for companies seeking to dominate the high-density power supply market with lower development costs and improved production yields.
