The MP2393 is a fully integrated, high-
frequency, synchronous, rectified, step-down,
switch-mode converter with internal power
MOSFETs. The MP2393 offers a very compact
solution that achieves 3A of continuous output
current with excellent load and line regulation
over a wide input range. The MP2393 uses
synchronous mode operation for higher
efficiency over the output current load range.
Constant-on-time (COT) control operation
provides 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), and thermal
The MP2393 requires a minimal number of
readily available, standard, external
components and is available in a space-saving
SOT583 (1.6mmx2.1mm) package.
