ISL8014AIRZ-T

ISL8014AIRZ-T is a ISL8014A is a high-efficiency, monolithic, synchronous step-down DC/DC converter that can deliver up to 4A continuous output current from a 2.8V to 5.5V input supply. It uses a current control architecture to deliver very low-duty cycle operation at high frequency with fast transient response and excellent loop stability. The ISL8014A can be configured for discontinuous or forced continuous operation at light load. Forced continuous operation reduces noise and RF interference while discontinuous mode provides high efficiency by reducing switching losses at light loads. Typical application includes 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, Li-ion battery powered devices, small form factor (SFP) modules, barcode readers.
