Product Description

The EV2269-D-00A demonstrates MPS’s MP2269, a fully-integrated, high efficiency, synchronous step-down switch mode converter with built-in high-side and low-side power MOSFETs. MP2269 provides up to 1A continuous output current over a wide input supply range with current mode control for fast loop response.

Full protection features include over-current protection (OCP) and thermal shutdown (TSD).

The Evaluation Board can deliver 1A continuous load current over a wide input range with excellent load and line regulation.

This part requires minimum number of external components and is available in QFN15 (2mmx3mm) package

IC Details

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 1? 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.
