DESCRIPTION
The DMS1067 is a monolithic step-down switch
mode converter with a built in internal power
MOSFET. It achieves 2A continuous output cur-
rent over a wide input supply range with excel-
lent load and line regulation.
The DMS1067 requires a minimum number of
readily available standard external components.
Current mode operation provides fast transient
response and eases loop stabilization.
Fault condition protection includes cycle-by-
cycle current limiting and thermal shutdown. In
shutdown mode the regulator draws 25µA of
supply current.
