The XZ1611 is a fixed-frequency current-modes Synchronous PWM step down converter that is capable of delivering 600mA of output current while achieving peak efficiency of 93%.Under light load conditions, the XZ1611 operates in a proprietary pulse skipping mode that consumes just 24uA of supply current, maximizing battery life in portable applications. The XZ1611 operates with a fixed frequency of 1.2MHz, minimizing noise in noise-sensitive applications and allowing the use of small external components. The XZ1611 is an ideal solution for applications powered by Li-lon batteries or other portable applications that require small board space.
The XZ1611 is available in a variety of fixed output voltage options, 1.5V,1.8V, 2.5V and is also available in an adjustable output voltage version capable of generating output voltage version from 0.6V to VIN. The XZ1611 is available in the tiny 5-pin SOT23-5L package.
