DEscriptION
The SL9486A is a high-voltage, step-down, switching
regulator that delivers up to 2A 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 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.
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 200μA quiescent current allows the SL9486A
to be used in battery-powered applications.
The SL9486A is available in ESOP8 package.
