Techcode® 2A 32V Synchronous Rectified Step-Down Converter DATASHEET TD1519 General Description Features The TD1519 is a monolithic synchronous buck • regulator. The device integrates two 90mΩ • MOSFETs, and provides 2A of continuous load current • over a wide input voltage of 4.75V to 32V. Current • mode control provides fast transient response • and cycle-by-cycle current limit. • An adjustable soft-start prevents inrush current at • turn-on, and in shutdown mode the supply current .

2A 32V Synchronous Rectified Step-Down Converter

Techcode® 2A 32V Synchronous Rectified Step-Down Converter DATASHEET TD1519 General Description Features The TD1519 is a monolithic synchronous buck • regulator. The device integrates two 90mΩ • MOSFETs, and provides 2A of continuous load current • over a wide input voltage of 4.75V to 32V. Current • mode control provides fast transient response • and cycle-by-cycle current limit. • An adjustable soft-start prevents inrush current at • turn-on, and in shutdown mode the supply current drops to 1µA. • This device, availablein an SOP8-PP package, • provides a very compact solution with minimal external • components. 2A Output Current Wide 4.75V to 32V Operating Input Range Integrated 90mΩ Power MOSFET Switches Output Adjustable from 0.923V to 30V 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 Applications • Distributed Power Systems • Networking Systems • FPGA, DSP, ASIC Power Supplies • Green Electronics/ Appliances • Notebook Computers Package Types October, 20, 2010.
