AT6300 Advance Resonant Controller Application
General Description
AT6300Z is a resonant controller IC to drive half bridge or full bridge base on ATK patented control
method to achieve superior dynamic and efficiency performance. With different setups on driver pin,
AT6300Z could operate in SRC/LLC half/full bridge architecture. For simplicity, this datasheet describes
SRC/LLC half/full bridge application only.
Synchronous rectifier control is provided to achieve high efficiency and to reduce system complexity. Besides programmable frequency, dead time between primary side drivers (TDPR) and load dependent delay time of secondary side driver (TDSR) are adjustable to further improve efficiency.
The AT6300Z also contains green frequency modulation (GFM) operation. It reduces switching duty cycle and frequency in light load to improve efficiency.
