BL9342 Datasheet | BELLING

40V, 600mA , Step-Down Converter Description 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. 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 BL9342 is available in SOT23-6L package. Features - 4.2 V to 40 V operating input range - 230uA...
