Overview
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.
