The General Assembly Shiping Group launches 2000W PFC digital power solution based on NXP products

Nowadays, the use of digital power has gradually spread to the fields of servers, communication equipment, car charging piles, and personal computers. Due to the increasing power of the current power supply, the product specification requirements are getting higher and higher. Due to hardware limitations, it is difficult for traditional analog power supplies to meet these requirements. Therefore, medium and high power power supplies are slowly changing from traditional analog control to Digital way to better realize the control, management and monitoring functions. The 2000W PFC digital power solution based on NXP MC56F81768 by UNGA Shiping can help engineers develop high-efficiency digital power easily.

On November 16, 2021, the leading Semiconductor component distributor dedicated to the Asia-Pacific region — Grand United Holdings announced that its subsidiary World Peace has launched a 2000W PFC digital power solution based on NXP (NXP) MC56F81768.

The main control chip of this program is the MC56F81768 MCU under NXP, which uses NXP’s self-developed 32-bit DSP core, with 128KB of Flash and 20KB of RAM, and a built-in 32KB of Boot ROM to support the use of UART and I2C code upgrade. In addition, the product also integrates two independent 12-bit ADCs, two independent operational amplifiers and four analog comparators. In terms of performance, it has been greatly improved compared to the previous product.
