一,产品概述(General Description) The JTML1482A is a monolithic synchronous buck regulator. The device integrates two 130mΩ SFETs, and provides2A of continuous load current over a wide input voltage of 4.75V to 23V.Current mode control provides fast transientresponse and cycle-by-cycle current limit.An adjustable soft-start prevents inrush current at turn-on, and inshuJTMLown mode the supply current drops to 1µA.This device, available in an SOP8 package, provides a very compactsolution with minimal external components 二.产品特点(Features) * 2AOutput Current * Wide 4.75V to 23V Operating Input Range * Integrated 130mΩ Power MOSFET Switches * Output Adjustable from 0.923V to 20V * Up to 93% Efficiency * Programmable Soft-Start * Stable with Low ESR Ceramic Output Capacitors * Fixed 340KHz Frequency * Cycle-by-Cycle Over Current Protection * Input Under Voltage Lockout 三,应用范围 (Applications) * Distributed Power Systems * Networking Systems * FPGA, DSP, ASIC Power Supplies * Green Electronics/ Appliances * Notebook Computers 四.下载产品资料PDF文档
