DESCRIPTION
The MP1660 is a fully integrated, highfrequency,
synchronous, rectified, step-down,
switch-mode converter with internal power
MOSFETs. The MP1660 offers a very compact
solution that achieves 3A of output current, with
excellent load and line regulation over a wide
input range. The MP1660 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
shutdown.
The MP1660 requires a minimal number of
readily available, standard external
components, and is available in a space-saving
SOT563 package.
