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 controller provides high efficiency by
switching the power MOSFETs at zero voltage, eliminating most
switching losses. The LLC controller is built around a current
controlled oscillator with a control range selected to support
the traditional frequency of operation found in televisions.
To ensure zero voltage switching, the dead time of the LLC
switching in the PLC810PG is tightly toleranced and can be
adjusted with an external resistor. The highside/lowside duty
cycle is also closely matched to provide balanced output
currents reducing output diode cost.
A typical PLC810PG LLC design operates at 100 kHz (under
nominal conditions). Depending on the LLC circuit design, the
switching frequency can vary from half to three times the nominal
operating frequency as a result of line and load changes.
The PFC converter is frequency locked to the LLC to minimize
noise and electromagnetic interference. Increasing the PFC
frequency in synchronization with the LLC at light loads
reduces the current at which the PFC boost converter

becomes discontinuous improving light load operation and
reducing power line harmonics. PFC and LLC primary side fault
management is provided.
The phase of the PFC PWM output is dynamically adjusted
relative to the LLC phase such that the switching edges do not
coincide with noise sensitive events in the PWM and LLC timing
circuits. This edge-collision avoidance technology simplifies
power supply layout and improves performance. Phase
synchronization reduces EMI spectral components and reduces
ripple current in the PFC capacitor.
