en.Wedoany.com Reported - WPG Holdings' Quanteng Group, in collaboration with onsemi, hosted an online seminar focusing on 75W to 160W power conversion solutions based on the NCP1945 integrated chip and the BCD65 TREO platform. This solution integrates high integration, high efficiency, and ease of mass production, aiming to support power upgrades for adapters, lighting equipment, and smart terminals.
As digital transformation accelerates across industries, traditional power design solutions face bottlenecks. At the seminar, onsemi Principal Engineer Gong Hongwen and Senior Product Marketing Manager Wang Bojue provided insights into the two core technologies. Gong Hongwen highlighted the NCP1945 chip, which integrates a critical conduction mode power factor correction controller with a quasi-resonant flyback controller, specifically designed for 75W-160W power converters. It supports a wide output voltage range, highly compatible with USB-C PD fast charging requirements, simplifying circuit architecture and reducing bill of materials and PCB layout workload.
The NCP1945 features low total harmonic distortion (THD), meeting global lighting industry energy efficiency and electromagnetic compatibility standards, and is available in four versions. In terms of power density optimization, when paired with miniaturized magnetic components, the chip reduces magnetic device volume by 20% compared to traditional solutions, PFC capacitor volume by 20% in 100W specifications, and RM8 transformer core volume by 40%. Integrated functions include clamped gate drive voltage, power drift mode, two-stage boost following, PFC valley synchronous frequency foldback, intelligent PFC start/stop, and quasi-resonant valley switching, helping reduce peripheral component count and overall power consumption. onsemi has simultaneously launched multiple reference designs covering 100W PD adapters, 70W LED lighting power supplies, and 140W dual-switch flyback PD power supplies.
Wang Bojue introduced onsemi's BCD65 TREO platform at the seminar. Based on advanced 65nm process technology, this platform is manufactured at onsemi's 300mm wafer fab in East Fishkill, New York, USA, featuring large-area cleanrooms and specialized backend packaging lines. The platform covers a wide voltage range from 1V to 90V, supporting the development of point-of-load power supplies, power management ICs, low-dropout linear regulators, and general-purpose analog devices, and can shorten product delivery and mass production cycles through IP reuse. Wang Bojue noted that several new products based on the TREO architecture have been sampled or released. Among them, the representative low-dropout linear regulator model T30LMPSR131 achieves a dropout voltage of only 25mV at 1A load, transient response speed at the microsecond level, operating temperature up to 175°C, and output voltage accuracy controlled between ±0.8% and ±1%. The platform also features integrated aliasing suppression chips, voltage conversion chips, and other products covering battery management, signal conversion, and power regulation scenarios.
The combination of the NCP1945 chip and the BCD65 TREO platform offers three key advantages: First, the NCP1945's total harmonic distortion performance helps products meet global energy efficiency standards; second, the chip's high integration simplifies bill of materials and PCB design, reducing circuit failure probability; third, the BCD65 TREO platform, leveraging mature processes and scalable production capacity, not only shortens the cycle from design to mass production but also, with its wide voltage range and high scalability, enables customers to quickly extend product lines based on existing solutions and explore more market opportunities.
WPG Quanteng Group stated that it will continue to collaborate with onsemi, focusing on power semiconductor technology iteration to drive the development of power solutions toward miniaturization, high efficiency, and energy savings. It is reported that since 2026, the former Pinjia, Quanteng, and Youshang groups have been integrated into the new Quanteng Group, aiming to assist customers in accelerating product launches and optimizing operational costs through digital supply chain management and technical support.
