HR1204
Digital PFC + LLC Combo Controller with Standby Power Input to VCC
Programmable Noise Suppression Filter
DESCRIPTION
The HR1204 is a high-performance controller that integrates an advanced, digital, PFC controller and a half-bridge, LLC resonant controller. The HR1204 requires low input power at no-load or ultra-light load, making it compliant with the Energy Using Product Directive (EuP) Lot 6 and Code of Conduct Version 5 Tier 2 specifications.
The PFC of the HR1204 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.
