MP1660 is a fully integrated, high frequency, 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), overcurrent protection (OCP), undervoltage protection (UVP) and thermal shutdown. The MP1660 requires a minimal number of readily available, standard external components and is available in a space-saving SOT-563 package. Typical applications include security cameras, digital set-top boxes, general purposes, flat-panel television and monitors.
