TD1484A

Techcode® DATASHEET 3.2A 23V Synchronous Rectified Step-Down Converte TD1484A General Description Features The TD1484A is a monolithic pulse-width-modulated (PWM) synchronous step-down switch mode regulator with two internal power MOSFETs. It achieves 3.2A continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limit and thermal shutdown. This device, available in an SOP8-PP package, provides a very compact solution with minimal external components. 3.2A Output Current Wide 4.75V to 20V Operating Input Range Integrated 90mΩ Power MOSFET Switches Output Adjustable from 0.923V to 20V Up to 93% Efficiency Programmable Soft-Start Stable with Low ESR CeramicOutputCapacitors Fixed 340KHz Frequency Cycle-by-Cycle Over Current Protection Input Under Voltage Lockout Applications Distributed Power Systems Networking Systems FPGA, DSP, ASIC Power Supplies Green Electronics/ Appliances Notebook Computers Package Types October, 20, 2010.
