MT1471
MT1471 is Synchronous Step-Down Converter manufactured by Aerosemi.
FEATURES - High Efficiency: Up to 96% - 500KHz Frequency Operation - 3A Output Current - No Schottky Diode Required - 4.5V to 16V Input Voltage Range - 0.8V Reference - Slope pensated Current Mode Control for Excellent Line and Load Transient Response - Integrated internal pensation - Stable with Low ESR Ceramic Output Capacitors - Over Current Protection with Hiccup-Mode - Thermal Shutdown - Inrush Current Limit and Soft Start - Available in SOT23-6 Package - -40°C to +85°C Temperature Range GENERAL DESCRIPTION The MT1471 is a fully integrated, high efficiency 3A synchronous rectified step-down converter. The MT1471 operates at high efficiency over a wide output current load range. This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load. The MT1471 requires a minimum number of readily available standard external ponents and is available in an 6-pin SOT23 ROHS pliant package. APPLICATIONS - Distributed Power Systems - Digital Set Top Boxes - Flat Panel Television and Monitors - Wireless and DSL Modems - Notebook puter TYPICAL APPLICATION VIN CIN 22μF C2 1u F L 10μH R1 100k 1% R2 19k 1% VOUT C1 22p F opt.
