AT6301Z Multi-Mode Resonant Controller in Interleaved Application
General Description
AT6301Z 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,AT6301Z could operate in single/interleaved SRC/LLC half/full bridge architecture. For simplicity, this datasheet describes interleaved 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 AT6301Z also contains green frequency modulation (GFM) operation. It reduces switching duty cycle and frequency in light load to improve efficiency.
