Product Information

The MP2269 is a frequency-programmable (350kHz to 2.5MHz), synchronous, step-down, switching regulator with integrated, internal, high-side and low-side power MOSFETs. The MP2269 provides 1A 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 MP2269 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 MP2269 is available in a QFN-15 (2mmx3mm) package.
