DC (Direct Current) DC converters are devices that convert DC electric power from one voltage level to another, and they are used in a variety of applications. The SUCW64812BP is a specialty DC converter, designed to provide high power conversion efficiency and wide input voltage range. This device is suitable for many applications including automotive and industrial applications.

The SUCW64812BP is a DC/DC converter with an isolated transformer, enabling a galvanic insulation between the power input and output. This feature makes the converter ideal for use in various safety and insulation applications, such as medical electronics, telecoms, or power supplies operating in potentially hazardous locations. The input voltage of this DC/DC converter ranges between 4.5V to 32V and the output voltage range is 0.8V – 5V.

This converter has 9 watt power rating, making it suitable to provide small load applications. It includes a forwarding circuit, allowing the converter to keep the output voltage even if the input voltage drops. In addition, its fixed frequency operation eliminates the need for an external control circuit. Furthermore, the inclusion of MOSFETs in the designs provides the user with overload and short-circuit protection against reverse polarity input voltage.

The SUCW64812BP from Murata uses a synchronous rectification technique, offering an efficiency of up to 90%. The minimal switching loss reduces operating temperatures, and increases efficiency. The converter also provides a low noise output, which meets the multi-output application requirements, and a wide temperature operating range of -40°C to +85°C.

The SUCW64812BP has wide applications in the field of automotive and industrial electronics. It can be used to generate low voltage power in automotive and industrial apparatus, such as IC testers, power supply equipment for inverters, drive control systems, and for auxiliary power connections. Additionally, the device can be used in solar power generation, wind energy systems, and embedded systems as well.

The DC/DC converter has a simple working principle; the input voltage is applied on the Input terminal, and is regulated by the applied MOSFETs. The input voltage is then amplified and filtered via an inductor, capacitors and switching FETs conduction, which is delivered to the output load. The output voltage is regulated by a closed loop feedback circuit designed with opto-couplers to ensure the accuracy of the output voltage.

The SUCW64812BP is a compact DC/DC converter designed with 9W power rating and advanced features including synchronous rectification technique and soft-start circuit with over voltage protection. The device is suitable for automotive and industrial applications. It offers a wide input voltage range as well as a low temperature operating range, making it an ideal choice for applications requiring high power conversion efficiency.
