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.
