DC DC Converters

DC-DC converters are electronic devices that convert a direct current (DC) voltage level to another DC voltage level. A DC-DC converter can operate either as step-up (boost) or step-down (buck). DC-DC converters are widely used in applications from providing power to a microprocessor to supplying auxiliary power to an electric vehicle. REC5-483.3SRWZ/H2/A/M/SMD/CTRL is a specific type of DC-DC converter used for precision analog circuits as well as for high speed switching. This converter features synchronous rectification and remote on/off control, making it suitable for a variety of applications.

• Data acquisition and control systems
• Industrial automation equipment
• Automotive power supplies
• Communication systems
• Medical instrumentation

Working Principle

The REC5-483.3SRWZ/H2/A/M/SMD/CTRL is a DC-DC converter using synchronous rectification, meaning it uses MOSFETs to switch the current instead of the traditional diode rectification. This makes the converter more efficient in comparison to other DC-DC converters. The converter also features a high conversion ratio, making it suitable for various applications. The converter uses a synchronous rectifier topology, meaning it uses two transistors, one on the high side and one on the low side, to switch the current.

The converter is powered from the input voltage and the switching frequency is usually in the range of a few hundred kilohertz. The switching frequency can be adjusted using an external resistor, allowing for better efficiency and the ability to change the output voltage more quickly in response to load changes. The converter also features an input voltage limit and an output voltage limit, allowing for better control of the output voltage.

The converter has a high efficiency due to its synchronous rectification and its current mode control. The current mode control ensures that the output voltage remains stable despite changes in the input voltage, allowing for better power supply stability. Additionally, the converter features a remote on/off control, allowing the output to be shut off if necessary.
