MP2263 Wide Input 3.3V - 30V, 3A, 12? IQ,Synchronous, Step-Down Converter with External Soft Start and Power Good in Small 2x3mm QFN Package

Product Detail

The MP2263 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 1? shutdown mode quiescent current allows the MP2263 to be used in battery-powered applications. High power conversion efficiency over a wide load range is achieved by scaling down the switching frequency at light-load condition to reduce switching and gate driving losses. An open-drain power good signal indicates the output. Frequency foldback helps prevent inductor current runaway during start-up. Thermal shutdown provides reliable and fault-tolerant operation. High-duty cycle and low drop-out mode are provided for battery-powered systems. The MP2263 is available in a QFN-15 (2mmx3mm) package.
