The Future of Analog IC Technology
MPS CONFIDENTIAL AND PROPRIETARY INFORMATION – SUPA USE ONLY
The MP1582 is a high frequency step-down
switching regulator with integrated internal
high-side, high voltage power MOSFET. It
Lprovides 2A output with current mode control
for fast loop response and easy compensation.
IAThe wide 4.5V to 28V input range
accommodates a variety of step-down
Tapplications, including those in automotive
systems. A 100µA operational quiescent current
allows use in battery-powered applications.
NHigh power conversion efficiency over a wide
Eload range is achieved by scaling down the
switching frequency at light load condition to
D Ereduce the switching and gate driving losses.
I TThe frequency foldback prevents inductor
current runaway during startup and thermal
Fshutdown provides reliable, fault tolerant
N BThe MP1582 is available in thermally enhanced
O ISOIC8 package.
