Catalog

The MP1682 is a fully integrated, high-frequency, synchronous, rectified, step-down switch-mode converter with internal power MOSFETs. The MP1682 offers a very compact solution that achieves up to 2A of continuous output current (I_OUT), with excellent load and line regulation across a wide input voltage (V_IN) range. The MP1682 uses synchronous mode for higher efficiency across the I_OUT 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 MP1682 requires a minimal number of readily available, standard external components, and is available in a space-saving SOT563 package.
