The SE1484 is a monolithic synchronous buck
regulator. The device integrates 95 mQ MOSFETS
that provide 3A continuous load current over
a wide operating input voltage of 4.5V
to
27V.Current mode control provides fast transient
response and cycle-by-cycle current limit.
An
adjustable sof-start prevents current at turn on.
