DESCRIPTION
FEATURES
The A7406A is
a
high frequency (1.8MHz)
4.2 V to 40 V operating input range
230uA operating quiescent current.
step-down switching regulator with integrated
internal high-side high voltage power MOSFET. It
provides single 0.6A(or less) highly efficient output
with current mode control for fast loop response.
The wide input range(4.2V to 40V) accommodates
a variety of step-down applications. Low shutdown
Low shutdown supply current

battery-powered applications.
High efficiency at light load condition is achieved by
scaling down the switching frequency to reduce the
switching and gate driving losses.
