Product Summary
The isl8009airz-t is a high efficiency, monolithic, synchronous step-down DC/DC regulator that can deliver up to 1.5A continuous output current. It is optimized for generating low output voltages down to 0.8V. The supply voltage range of 2.7V to 5.5V, allows the use of single Li+cell, three NiMH cells or a regulated 5V input. The isl8009airz-t uses current mode control architecture to deliver very low duty cycle operation at high frequency with fast transient response and excellent loop stability. The applications of the isl8009airz-t include DC/DC POL Modules, μC/μP, FPGA and DSP Power, Plug-in DC/DC Modules for Routers and Switchers, Portable Instruments, Test and Measurement Systems.
