DESCRIPTION:

The SY3167 is a monolithic step-down switchmode converter with a built in internal powerMOSFET. It achieves 2A continuous output currentover a wide input supply range with excellentload and line regulation.The SY3167 requires a minimum number ofreadily available standard external components.Current mode operation provides fast transientresponse and eases loop stabilization.
Fault condition protection includes cycle-bycyclecurrent limiting and thermal shutdown. In shutdown mode the regulator draws 25μA of supply current.
