The AT1368 provides complete control and protection of DC/DC converters optimized for high performance microprocessor applications. It is designed to drive one P-channel and one N-channel MOSFET in a synchronous rectified buck topology. The AT1368 integrates all control, output regulation, monitoring and protection functions into a single package. "The converter's output voltage can be precisely regulated with a maximum tolerance of ±2% over temperature and line voltage variation." The AT1368 is a low noise synchronous step-down home DC/DC converter ideal for powering from a 1-cell Li-ion battery or Systems from 3-cell 4-cell NiCd, NiMH or Alkaline batteries. It can also be used for USB based power systems.
