STMicroelectronics DCP3603 3A Synchronous Buck Converters
STMicroelectronics DCP3603 3A Synchronous Buck Converters are wide-input voltage, easy-to-use synchronous buck converters that can drive up to 3A load current. The extended input range from 3.3V to 36V makes the device suitable for a wide range of industrial applications. The STMicroelectronics DCP3603 operates at either 500kHz or 1.0MHz fixed switching frequency, allowing the use of small inductors for an optimized solution size. Optional switching frequency dithering is implemented to improve EMI performance. It is based on a peak current mode architecture, including soft-start circuit, overcurrent protection circuit, overtemperature protection, output overvoltage protection, and is packaged in a SOT-23-6L package.
