30V 3A LOW IQ SYNC BUCK

The MP2263 is a frequency programmable, (350k to 2.5MHz) synchronous step-down, switching regulator with integrated internal high-side and low-side power MOSFETs. It provides a 3A highly efficient output with current mode control for fast loop response. The wide 3.3V to 30V input voltage range accommodates a variety of step-down applications in automotive input environments. A 1µA shutdown mode quiescent current allows for use in battery-powered applications.High power conversion efficiency over a wide load range is achieved by scaling down the switching frequency at a light-load condition to reduce the switching and gate driving losses. The MP2263 is available in QFN-15 (2mmx3mm) package.
