The MP1463 is a frequency-programmable (350kHz to 2.5MHz), synchronous, step-down, switching regulator with integrated, internal, high-side and low-side power MOSFETs. The MP1463 provides 3A of highly efficient output current with current-mode control for fast loop response.

The wide 3.3V-to-19V input range accommodates a variety of step-down applications. A 1μA shutdown mode quiescent current allows the MP1463 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 signal.

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 MP1463 is available in a QFN-15 (2mmx3mm) package.
