NCP1681AAD2R2G, ON Semiconductor
The ON Semiconductor NCP series of a PFC controller IC designed to drive the bridgeless totem-pole PFC topology. The bridgeless totem-pole PFC is a power factor correction architecture that consists of a fast switching leg driven at the PWM switching frequency and a second leg that operates at the AC line frequency. This topology eliminates the diode bridge present at the input of a conventional PFC circuit, allowing significant improvement in the power stage efficiency.
Enables high efficiency & compact design
Skip mode in very light load condition
Near unity power factor in all operating modes

NCP1618DDR2G, ON Semiconductor
The ON Semiconductor NCP1618DDR2G is an innovative multimode power factor controller. The circuit naturally transitions from one operation mode to another depending the switching period duration so that the efficiency is optimized over the line/load range. In very−light−load conditions, the circuit can enter the soft−SKIP mode for minimized losses. Housed in a SO-9 package, the circuit further incorporates the features necessary for robust and compact PFC stages, with few external components

NCP1632ADR2G, ON Semiconductor
The ON Semiconductor NCP series of an integrated dual mosfet driver for interleaved PFC applications. Interleaving consists of paralleling two small stages in lieu of a bigger one, more difficult to design. This approach has several merits like the ease of implementation, the use of smaller components or a better distribution of the heating. Also, Interleaving extends the power range of critical conduction mode that is an efficient and cost-effective technique.
