RDF5072WS12

DC/DC converters are electrical components that convert power from one form of DC voltage to another. The RDF5072WS12 is a monolithic step-down DC/DC converter industry-standard size with a low profile package and a power supply of up to 0.6A. It is an excellent choice for battery-powered applications as it offers high efficiency and good power density at a very reasonable cost. It is ideal for applications such as consumer electronics, automotive, telecom, networking, and embedded applications.

The RDF5072WS12 is a synchronous step-down converter that uses the industry-standard Fixed Frequency PWM Control (FFPC) approach to regulate the output voltage. It features a wide input voltage range from 4.0V to 16V and an adjustable output voltage range from 0.60V to 12V. The internal high-frequency regulator allows for fast transient response times, ensuring stable output voltage for a wide range of line, load, and temperature changes. The internal compensation network provides fast, stable loop response with minimal external components.

The RDF5072WS12 features a wide operating temperature range of -40°C to +150°C, making it suitable for a variety of environmental conditions and assuring reliable operation from cold start-up to high ambient temperatures. The under-voltage lockout (UVLO) feature helps protect the device from under-voltage faults, enabling it to operate reliably within its specified input voltage range.

The RDF5072WS12 requires no external components other than input and output capacitors, making it easier to design and assemble. The integrated soft-start function automatically starts-up the converter, reducing start-up current surges and easing the system start-up process. Additionally, a built-in accurate OTP (overtemperature protection) circuit ensures against thermal overstress of the device by monitoring the junction temperature and providing an orderly shutdown.

The RDF5072WS12 is designed to be robust, highly efficient, and low cost, making it an ideal choice for cost-sensitive, battery-powered applications. It offers high efficiency from 95% at no-load and 85% at full-load. This converter is an efficient, reliable, and affordable solution for a wide range of DC/DC conversion needs in consumer, industrial, and automotive applications.
