automotive applications. The integrated circuit (IC) incorporates a
switching regulator, which operates over a wide input voltage range
from 4.5 to 26.5 V.
voltage mode control. It has a 3.5 A current limit (typical) and the slew-
rate is adjustable via a control pin to reduce switching noise. The
switching regulator has an adjustable frequency oscillator, which
allows the user to optimize its operation over a wide range of input
voltages and component values.
