TD1484

T  echcode® DATASHEET       3A 23V Synchronous Rectified Step-Down Converter TD1484 General Description  Features    The TD1484 is a monolithic synchronous buck    3A Output Current regulator. The device integrates two 90mΩ    Wide 4.75V to 23V Operating Input Range MOSFETs, and provides 3A of continuous load current    Integrated 90mΩ Power MOSFET Switches over a wide input voltage of 4.75V to 23V. Current    Output Adjustable from 0.923V to 20V mode control provides fast transient response    Up to 93% Efficiency and cycle-by-cycle current limit.    Programmable Soft-Start An adjustable soft-start prevents inrush current at turn-on, and in shutdown mode the supply current    Stable with Low ESR Ceramic Output Capacitors drops to 1µA.    Fixed 340KHz Frequency This device, availablein an SOP8-PP package,    Cycle-by-Cycle Over Current Protection provides a very compact solution with minimal external    Input Under Voltage Lockout components.  Applications     Distributed Power Systems    Networking Systems    FPGA, DSP, ASIC Power Supplies    Green Electronics/ Appliances Notebook Computers Package Types                    Figure 1. Package Types of TD1484  October,  20,  2010.                                                        Techcode  Semiconductor  Limited                                                  www.techcodesemi.com  1  T  echcode®       3A 23V Synchronous Rectified Step-Down Converter Pin Configurations  DATAS...
