MP1476L 3.9V-18V, 2A, 800kHz High-Efficiency, Synchronous, Step-Down Converter In a SOT563 Package DESCRIPTION FEATURES The MP1476L is a fully integrated, high- Wide 3.9V to 18V Operating Input Range frequency, synchronous, rectified, step-down, 126m/58m Low R Internal Power DS(ON) switch-mode converter with internal power MOSFETs MOSFETs. The MP1476L offers a very 190A Low I Q compact solution that achieves 2A of High-Efficiency Synchronous Mode continuous output current with excellent load Operation and line regulation over a wide input range. The Power-Save Mode (PSM) at Light Load MP1476L uses synchronous mode operation Fast Load Transient Response for higher efficiency over the output current-load 800kHz Switching Frequency range. Internal Soft Start (SS) Constant-on-time (COT) control operation Over-Current Protection (OCP) and Hiccup provides very fast transient response, very tight Thermal Shutdown output regulation, and eases loop design. Output Adjustable from 0.8V Available in a SOT563 Package Full protection features include short-circuit protection (SCP), over-current protection (OCP), APPLICATIONS under-voltage protection (UVP), and thermal Security Camera shutdown. Digital Set-Top Boxes The MP1476L requires a minimal number of Flat-Panel Television and Monitors readily available, standard, external General Purposes Power Supplies components and is available in a space-saving All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive.
