The CXSD62389 is a monolithic step-down switch mode regulator with a built in internal power MOSFET. It achieves 3A continuous output current over a wide input supply range with excellent load and line regulation. The wide 4.5V to 28V input range accommodates a variety of step-down applications, including those in an automotive input environment. A 180μA operational quiescent current allows use in battery-powered applications. High power conversion efficiency over a wide load range is achieved by scaling down the switching frequency at light load condition to reduce the switching and gate driving losses. The frequency foldback helps prevent inductor current runaway during startup and thermal shutdown provides reliable, fault tolerant operation. By switching at 1.5MHz, the CXSD62389 is able to prevent EMI (ELECTROMAGNETIC Interference) noise problems, such as those found in AM radio and ADSL applications. The CXSD62389 requires a minimum number of readily available standard external components. It is available in a DIP-8, SOP-8 (FD) and TDFN3X3-8 package.
