PFC Controller Offers 500 W Power Factor
Operating at a constant frequency in continuous and discontinuous conduction modes, Power Factor One’s PF8803 power factor correction (PFC) controller helps designers gain near unity power factor from 75 W to 500 W. The 8-lead SOIC- and DIP-packaged component exhibits a 0.99 typical power factor, <7% harmonic distortion, 88% typical efficiency, and output voltage regulation. The mixed-signal CMOS-designed controller can be used in AC/DC boost pre-regulator, single-stage flyback converter, and SSLD applications. The device includes an analog reset system, voltage ramp driver, automatic soft startup, undervoltage and overvoltage protection, and current limiting.
