DESCRIPTION

The A7406A is a high frequency (1.8MHz) 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 mode quiescent current allows use in 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.

The A7406A is available in SOT-26 package.
