n Description n FeaturesPT2580is a family of a high performancePrimarySide Regulation (PSR) power switch with highprecision CV/CC control ideal for chargerapplications. The IC can also supportQuasi-Resonant (QR) Buck constant currenttopology for LED lighting if SEL pin is short toGND. In CV mode,PT2580 adopts Multi ModeControl which uses the hybrid of AM (AmplitudeModulation) mode and (Frequency Modulation)FM mode to improve system efficiency andreliability. In CC mode, the IC uses PFM controlwith line and load CC compensation. The IC canachieve audio noise free operation andoptimized dynamic response. The built-in CableDrop Compensation (CDC) function can provideexcellent CV performance. PT2580 integratesfunctions and protections of Under VoltageLockout (UVLO), VDD over Voltage Protection(VDD OVP), Cycle-by-cycle Current Limiting(OCP), Short Load Protection (SLP), and VDD ?
