General description
The UCC28180 is a flexible and easy-to-use, 8-pin,active Power-Factor Correction (PFC) controller thatoperates under Continuous Conduction Mode (CCM)to achieve high Power Factor, low current distortionand excellent voltage regulation of boost preregulators in AC - DC front-ends. The controller issuitable for universal AC input systems operating in100-W to few-kW range with the switching frequencyprogrammable between 18 kHz to 250 kHz, toconveniently support both power MOSFET and IGBTswitches. An integrated 1.5-A and 2-A (SRC-SNK)peak gate drive output, clamped internally at 15.2 V(typical), enables fast turn-on, turn-off, and easymanagement of the external power switch without theneed for buffer circuits.Low-distortion wave shaping of the input currentusing average current mode control is achievedwithout input line sensing, reducing the externalcomponent count. In addition, the controller featuresreduced current sense thresholds to facilitate the useof small-value shunt resistors for reduced powerdissipation, especially important in high-powersystems. To enable low current distortion, thecontroller also features trimmed internal current loopregulation circuits for eliminating associatedinaccuracies.
