DESCRIPTION
The EV2359DJ-00B is the evaluation board for
the MP2359, a monolithic non-synchronous
step-down switch mode converter with an
integrated power MOSFET.
The MP2359 achieves 1.2A 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.
The MP2359 is available in TSOT23-6 and
SOT23-6 packages.
