A new addition has been made to ON Semiconductor’s solution set for ultra-high density offline power supplies in the form of the NCP1680, a dedicated critical conduction mode totem pole PFC controller. It can accommodate any switch type, whether it’s a super-junction silicon MOSFET or wide-bandgap switches such as silicon carbide (SiC) or gallium nitride (GaN) devices.
The device employs a novel current limit architecture and line phase detection while incorporating proven control algorithms to deliver a cost-effective solution without compromising on performance. At the heart of this IC is an internally compensated digital loop control and it employs a constant on-time CrM architecture with valley switching. Modern efficiency standards, including those that require high efficiency at light load, can also be met due to inbuilt discontinuous conduction mode (DCM) with valley synchronised turn-on during frequency foldback operation.
This highly integrated device can enable power supply designs that operate with universal mains (90-265 V a.c.) at recommended power levels up to 350 W.
