HiperPLC - Continuous Mode PFC & LLC Controller with
Integrated Half Bridge Drivers
HiperPLC ImageThe HiperPLC™ is a combined PFC and LLC off-line controller with an integrated hi-side/lo-side high voltage half bridge driver. The PFC section of the HiperPLC supports a universal input, continuous-current mode (CCM) topology that does not require a sinusoidal input reference.

The DC-DC controller supports 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 frequency of operation found in LCD TV.     Datasheet
