MP1477HGTF-P

MP1477HGTF-P is a high-efficiency, fully integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. The MP1477H offers a very compact solution that achieves 3A of continuous output current with excellent load and line regulation over a wide input range. The MP1477H uses synchronous-mode operation for higher efficiency over the output current-load range. The 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. Typical applications include security cameras, digital set-top boxes, flat-panel television and monitors, and general purposes.
