The NCP1680ABD1R2G with Power Factor Correction - PFC HIGH VOLTAGE POWER FACTOR CORRECTION CONTROLLER is a high voltage, high-accuracy, current-mode controller manufactured by ON Semiconductor. It is designed for AC/DC power factor correction applications such as SMPS,s for telecom, DIN rail mount, or walled mounts. Features include adjustable frequency, leading or trailing-edge dimming and PFC boost/discontinuous current mode (DCM) operation. The NCP1680ABD1R2G can be used for input voltages of up to 600V, providing a precise dynamic loop with superior transient response. The NCP1680ABD1R2G packaged in a thermally enhanced, space-saving SOIC-8 with an exposed pad.
