Description
The MP2348 is a fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a compact solution to achieve 4A of continuous output current across a wide input range, with excellent load and line regulation. The MP2348 has synchronous mode operation for higher efficiency across the output current load range.
Constant-on-time (COT) control provides fast transient response and easy loop design, as well as tight output regulation.
Full protection features include short-circuit protection (SCP), over-current protection (OCP), under-voltage protection (UVP), and thermal shutdown.
The MP2348 requires a minimal number of readily available, standard external components, and is available in a space-saving SOT583 (1.6mmx2.1mm) package.
