BL9342 Overview
The BL9342 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) acmodates a variety of step-down applications.
