Description :

The MP1582EN is a high frequency step-down switching regulator with integrated internal high-side, high voltage power MOSFET. It provides 2A 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 automotive systems. 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.

Features :

The frequency foldback prevents inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation.  SOIC8 package.
