Overview
This demo board uses the NCP1681 CCM multi-mode PFC controller,
the latest current mode LLC controller NCP13994, and the NCP4318 SR
controller for low profile and small dimension design, enabling
high power density PSU without FAN cooling.
The NCP13994 is a high-performance current mode controller for
half bridge resonant converters. This controller implements 700 V
gate drivers, simplifying fast response green mode then VPFC hiccup
between 395 V to 410 V.

Overview This demo board uses NCP1681 CCM multi-mode PFC
controller, latest current mode LLC controller NCP13994, and NCP4318 SR
controller for low profile and small dimension design, enabling high power
density PSU without FAN cooling.
The NCP1681 is a PFC controller IC designed to drive the bridgeless totem pole
PFC topology. The bridgeless totem pole PFC is a power factor correction
architecture that consists of a fast leg driven at the PWM switching frequency
and slow leg that operates at the AC line frequency. This topology eliminates
the diode bridge and significant improvement in the power stage efficiency,
especially at low line. The controller can be configured to operate in
continuous conduction mode (CCM) or multi-mode (CrM-CCM) operation.
The NCP13994 is a high performance current mode controller for half bridge
resonant converters. This controller implements 700 V gate drivers,
simplifying

layout and reducing external component count. The built-in Brown-Out input function eases implementation of the controller in all applications. In applications where a PFC front stage is needed, the NCP13994 features a dedicated output to drive the PFC controller. This feature together with quiet skip mode technique further improves light load efficiency of the whole application.
NCP4318 is an advanced Synchronous Rectification (SR) controller for LLC resonant converter with minimum external components. It has two driver stages for driving the SR MOSFETs which are rectifying the outputs of the secondary transformer windings. The two gate driver stages have their own Drain and Source sensing inputs and operate independently of each other. The advanced adaptive dead time control compensates parasitic inductance voltage to minimize the body diode conduction and maximize the efficiency. The advanced turn-off control algorithm allows stable SR operation over entire load range.
