MP1584 Step Down 3 Ampere Adjustable Regulator Module

This DC to DC Buck/step-down voltage converter module is based on MP1584 IC from Monolithic Power Systems, it converts input voltage between 4.5V and 28V into a smaller voltage between 0.8V and 18V, capable of driving a 3 Ampere load with excellent line and load regulation.

MP1584 is a high frequency step-down switching regulator with an integrated internal high-side high voltage power MOSFET. MP1584 provides 3A output with current mode control for fast loop response and easy compensation.   The wide 4.5V to 28V input range accommodates a variety of step-down applications, including those in an automotive input environment. A 100µA operational quiescent current allows use 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 the switching and gate driving losses.
