3.3V to 30V Input, 3A-Output, 12µA IQ, Synchronous, Step-Down Converter

The MP2263 from Monolithic Power Systems, Inc. (MPS) is a frequency-programmable (350kHz to 2.5MHz), synchronous, step-down, switching regulator with integrated, internal, high-side and low-side power MOSFETs. The MP2263 provides 3A of highly efficient output current with current-mode control for fast loop response.

The wide 3.3V-to-30V input range accommodates a variety of step-down applications. A 1µA shutdown mode quiescent current allows the MP2263 to be used in battery-powered applications including smart homes, wide-input range power supplies, standby power supplies, and so on.
