DESCRIPTION
The MP2328 is a fully integrated, highfrequency, synchronous, rectified, step-down
switch-mode converter with internal power
MOSFETs. It offers a very compact solution to
achieve 2A of continuous output current across
a wide input range, with excellent load and line
regulation. The MP2328 has synchronous
mode operation for high efficiency across the
wide output current load range.
Constant-on-time (COT) control provides very
fast transient response and easy loop design,
as well as tight output regulation.
Full protection features include short-circuit
protection (SCP), over-current protection (OCP),
under-voltage protection (UVP), and thermal
shutdown.
The MP2328 requires a minimal number of
readily available, standard external components.
It is available in a space-saving SOT583
package.
