2A, 1.4MHz Step-Down Converter
Evaluation Board

DESCRIPTION
The EV2361DK/DQ-00A is the evaluation board
for the MP2361, a monolithic step down switch
mode converter with a built in internal power
MOSFET.
The
MP2361
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 20µA of
supply
current.
Programmable
soft-start
minimizes the inrush supply current and the
output overshoot at initial startup.
The MP2361 requires a minimum number of
readily available standard external components.
