[Introduction]May 25, 2022—Onsemi (onsemi, NASDAQ: ON), a leader in intelligent power and intelligent sensing technology, will hold a live webinar in Mandarin in Greater China, explaining company-specific Advanced mixed-signal controller in bridgeless totem-pole power factor correction (TP PFC) topology.
The technical webinar, titled “Totem Pole PFC Technology Empowers More Energy Efficient Power Supplies”, will be live on June 23 at 10:00 am China time, introducing how TP PFC technology can improve power efficiency without complexity.
ON semiconductor will talk about the NCP1681 for ultra-high density offline power supplies. The new controller builds on the success of the NCP1680 for designs up to 350 W, extending power capability into the kilowatt range.
In the past, TP PFC designs required the use of an MCU, which added complexity to the design and required coding. Now with the NCP1681, a full-featured TP PFC scheme can be implemented without coding by adding only a few external components, saving time, cost, and footprint.
The NCP1681 high-power TP PFC controller combines mature control algorithms and novel functions to provide high-performance and cost-effective TP PFC solutions.
The controller can be configured to operate in fixed frequency continuous conduction mode (CCM) or multi-mode, switching naturally between CCM and critical conduction mode (CrM) for optimal performance at various power levels.
The NCP1681 is suitable for higher power supplies in the 350 W to multi-kilowatt range, operates from universal power input (90 – 265 Vac), and is suitable for a wide range of applications including server, high performance computing, telecom, industrial and OLED TVs. Under high voltage input, the energy efficiency of NCP1681 TP PFC scheme will reach nearly 99%.
