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.
