1.5A, 23V, 1.4MHz Dual
Step-Down Converter Evaluation Board

GENERAL DESCRIPTION
The EV2364DF-00A is an evaluation board for
the MP2364, a dual output, monolithic
step-down switch mode converter with built-in
internal power MOSFETs. It achieves 1.5A
continuous output current for each output 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 40µA of
supply current.
The MP2364 requires a minimum number of
readily available standard external components.
