TD1482A

Techcode® 2A 20V Synchronous Rectified Step-Down Converte DATASHEET TD1482A General Description Features The TD1482A is a monolithic pulse-width-modulated (PWM) synchronous step-down switch mode regulator with two internal power MOSFETs. It achieves 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 package, provides a very compact solution with minimal external components. 2A Output Current Wide 4.75V to 20V Operating Input Range Integrated 130mΩ Power MOSFET Switches Output Adjustable from 0.923V to 18V 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.
