MP2263GD-Z

1. DESCRIPTION

The MP2263GD-Z is a frequency-programmable (350kHz to 2.5MHz), synchronous, step-down, switching regulator with integrated, internal, high-side and low-side power MOSFETs. The MP2263GD-Z 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 MP2263GD-Z 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 MP2263GD-Z is available in a QFN-15 (2mmx3mm) package.
