In the past, TP PFC designs required the use of an MCU that added design complexity and the need for coding. However, with the NCP1681, only a few external components and no coding is needed to be added for a fully-featured TP PFC solution, thereby saving time, cost and space.
Commenting on the new release,
The NCP1681 can be configured to work in either fixed frequency continuous conduction mode (CCM) or multi-mode operation, where the controller naturally transitions between CCM and critical conduction mode (CrM) for optimal performance across power levels.
The new NCP1681 high power TP PFC controller integrates established control algorithms with novel features to deliver a high performance and cost-effective TP PFC solution. Challenging efficiency standards such as '80Plus' or 'CoC Tier 2', that require high efficiency over a wide load range, can also be met.
The new NCP1681 is suited to higher-power power supplies from 350 W to several kilowatts range that operate on universal mains input (90 - 265 Vac), addressing a wide range of applications including server, high performance computing, telecom, industrial and OLED TV. At high line, NCP1681 TP PFC solutions will achieve close to 99% efficiency.
The NCP1681 will be demonstrated alongside the award-winning lower power (
