DESCRIPTION
The MP2319 is a fully-integrated, high-
frequency, synchronous, rectified, step-down,
switch-mode converter with internal power
MOSFETs. The MP2319 offers a very compact
solution that achieves 3A of continuous output
current with excellent load and line regulation
over a wide input range. The MP2319 has
synchronous mode operation for higher
efficiency over the output current load range.
Constant-on-time control operation provides a
very fast transient response, easy loop design,
and very tight output regulation.
Full protection features include short-circuit
protection (SCP), over-current protection (OCP),
under-voltage protection (UVP), over-voltage
protection (OVP), and thermal shutdown.
The MP2319 requires a minimal number of
readily available, standard, external
components and is available in a space-saving,
8-pin, TSOT23 package.
