I'm considering bridgeless totem-pole PFC for a design and am looking for the quickest integrated solution. Unfortunately, it seems like a lot of implementations currently use MCUs and DSPs for control of the MOSFET drivers. While it is a a valid solution, it requires additional workload.
This far the integrated options I have found are:
And possibly ICE3PCS01G in certain configurations. Are there any other upcoming or existing integrated options?
Currently, as of March 2023 few manufacturers offer integrated solutions for bridgeless totem pole PFC.
The three main design choices are:
Available integrated solution: NCP1680, NCP1681, IMC102T-F048, MPF32010.
MCU/DSP with or without integrated support features. Evaluation designs use circuits like STM32F334, F28004x, UCD3138, TMS320F28335, MC56F83783.
Boost PFC circuits in combination with externa logic such as can be seen in EVAL_2500W_PFC_GAN_A.
A good way to choose a design is to view and test available totem pole PFC evaluation boards that many major manufacturers offer.
