40V 600mA Step-Down Regulator AT9342
AT9342 is a high-frequency (1.8MHz) buck-type switch regulator with internal integration of high-side high-voltage power MOSFET. It offers a maximum efficient output of 0.6A for a single channel, achieving rapid loop response through current mode control.
A wide input voltage range (4.2V to 40V) enables various applications for buck-type power conversion. The low quiescent current is suitable for battery-powered scenarios.
Under light load conditions, efficiency within a wide load range is achieved by reducing switch frequency to minimize losses in both the switch and gate driver. Frequency folding technology helps prevent uncontrolled inductor current during startup. Thermal shutdown ensures reliable and fault-tolerant operation. The AT9342 is packaged in an SOT23-6L package.
