Techcode® DATASHEET 2A 32V Synchronous Rectified Step-Down Converter TD1519A General Description Features The TD1519A 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 [ ... ]
