PLC810PG

PLC810PG HiperPLC™ Family Continuous Mode PFC & LLC Controller with Integrated Half-bridge Drivers Product Highlights Features Highly integrated, eliminates external components Frequency and phase synchronized PFC and LLC Reduced noise and EMI Ripple current reduction in PFC output capacitor Edge collision-avoidance simplifies layout Comprehensive PFC and LLC fault handling and current limiting Proprietary continuous conduction mode PFC for high efficiency with low component cost High efficiency Zero Voltage Switching (ZVS) LLC Off-time PFC control eliminates AC input sensing components Configurable, precise dead time control and frequency limit Prevents hard MOSFET switching Tight LLC duty cycle symmetry for balanced O/P diode currents Lead and halogen free Green package Applications 32” to 60” LCD TV power supplies Off-line 150 W to 600 W efficiency-optimized power supplies LED street lighting Description The PLC810PG is a combined PFC and LLC off-line controller with integrated high voltage half-bridge drivers. Figure 1 shows a simplified schematic of a PLC810PG based power supply where the LLC resonant inductor is integrated into the transformer. The PFC section of the PLC810PG is a universal input continuous current mode (CCM) design that does not require a sinusoidal input reference, thereby reducing system cost and external components. The DC-DC controller drives an LLC resonant topology. This variable frequency controlle...
