DESCRIPTION

The MP9486A is a high-voltage, step-down,

switching regulator that delivers up to 1A of

continuous current to the load. It integrates a

high-side, high-voltage, power MOSFET with a

current limit of 3.5A, typically. The wide 4.5V to

100V input range accommodates a variety of

step-down applications, making it ideal for

automotive, industry, and lighting applications.

Hysteretic voltage-mode control is employed for

very fast response. MPS’s proprietary feedback

control scheme minimizes the number of

required external components.

The switching frequency can be up to 1MHz,

allowing for small component size. Thermal

shutdown and short-circuit protection (SCP)

provide reliable and fault-tolerant operations. A

170µA quiescent current allows the MP9486A

to be used in battery-powered applications.

The MP9486A is available in a SOIC-8 package

with an exposed pad.
