PLC810PG - Continuous Mode PFC & LLC Controller

General 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.

Key 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.
