The MP2319 is a fully-integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. The MP2319 offers a very compact solution that achieves 3A of continuous output current with excellent load and line regulation over a wide input range. The MP2319 has synchronous mode operation for higher efficiency over the output current load range. Constant-on-time control operation provides a 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), over-voltage protection (OVP), and thermal shutdown. The MP2319 requires a minimal number of readily available, standard, external components and is available in a space-saving, 8-pin, TSOT23 package.
