DESCRIPTION
The EV2364DF-01A 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.
The MP2364’s current mode operation provides
fast transient response and eases loop
stabilization.
Its fault protection includes cycle-by-cycle current
limiting and thermal shutdown. In shutdown mode
the regulator draws 40µA of supply current.
