The Analog Devices AD637JRZ is a power management specialized, RMS/DC Converter Integrated Circuit (IC), designed with PMIC technology. It is a complete, autoranging, high performance power converter, combining an RMS-sensing input current with an on-chip voltage regulator. It can process signals with an input voltage range of 3.75 V to 40 V and is capable of delivering up to 1.0 A of output current from a light load up to a full load. The device operates on power supplies from 6.15 V to 19.2 V and can peak at a maximum current of 1.3 A for short-term peak exposure. The IC offers 90% minimum efficiency over its entire operating range, and is suitable for many power sensitive applications, including automotive and industrial systems. It also comes with features such as zero crossover operation, low EMI performance and built-in protection.
