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. The MP2269 provides up to 1A of 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). It requires minimum number of external components, and is available in a QFN-15 (2mmx3mm) package.

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

Parametrics

Wide Input 3.3V - 30V, 1A, 12µA I_Q , Synchronous, Step-Down Converter with External Soft Start and Power Good in Small 2x3mm QFN Package

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.
