Monolithic Power Systems
General Description
The EV0007 is a 2A evaluation board based on
the MP1580 DC to DC Converter. The MP1580
is a monolithic step down switch mode
converter with a built in internal Power
MOSFET. It achieves 2A continuous output
current over a wide input supply range with
excellent load and line regulation.
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 23µA of
supply current.
The MP1580 requires a minimum number of
readily available standard external components.
A synchronization pin allows the part to be
driven to 600KHz.
