HR1200 High-Performance Digital PFC+LLC Combo Controller NOT RECOMMENDED FOR NEW DESIGNS. REFER TO HR1203 DESCRIPTION The HR1200 is a high-performance controller that integrates an advanced digital PFC controller and a half-bridge LLC resonant controller. It requires quite low input power at no load or ultra-light load, making it compliant with Energy using Product Directive (EuP) Lot 6 and Code of Conduct Version 5 Tier 2 specifications. The PFC of the HR1200 employs a patented average current control scheme, which can operate both in continuous conduction mode (CCM) and discontinuous conduction mode (DCM) according to the instantaneous condition of the input voltage and output load. The IC exhibits excellent efficiency and high power factor (PF) at light load.
