DC DC converters are electronic systems which convert a high voltage direct current (DC) input to one or more lower voltage DC outputs. These outputs may differ in voltage magnitude and even polarity. DC DC converters can provide isolated outputs through one or more galvanically isolated transformers. RP20-483.3SAW/N is an example of a DC DC converter.

The RP20-483.3SAW/N converter is a high efficiency isolated isolated flyback converter with a nominal input voltage of 48 VDC and a nominal output of 3.3 VDC. This converter supports up to 35 W of output power and combines high efficiency and small size to perfectly meet the requirements of many applications. Typical applications include industrial automation, networking and telecom, communications, medical instrumentation, LED lighting, and more.

The working principle of the RP20-483.3SAW/N converter is based on the flyback topology. This topology is commonly used for low to medium power applications and delivers high efficiency while providing electrical isolation between the input and output. The basic principle of operation for the flyback topology is the coupling of energy from the input circuit to the output circuit with a transformer. This transformer enables electrical isolation and provides galvanic isolation between the input and output.

The converter operates by first extracting energy from the input and storing it in an inductor via a self-biased switch. This switch is usually driven by a pulse width modulated (PWM) control signal. The stored energy is then transferred to the output via the transformer winding and diode rectifier. During this process, the output voltage is regulated to its specific set point. An integrated feedback loop is used to ensure that the output voltage stays at its predetermined value.

The RP20-483.3SAW/N converter has several other features that make it the ideal choice for a wide range of applications. First, the converter is designed with an integrated output voltage sense network that greatly reduces the external component count. This helps to keep the overall size of the converter to a minimum. Additionally, the converter contains integrated ORing and synchronous rectification circuitry for high efficiency, as well as integrated EMI noise filtering for meeting the most stringent EMI requirements.

The RP20-483.3SAW/N converter is a versatile and reliable solution for a variety of applications. Its combination of high efficiency, small size, and low external component count makes it the perfect choice for industrial automation, networking and telecom, communications, medical instrumentation, LED lighting, and other applications. By utilizing the flyback topology, this converter provides electrical isolation as well as great performance and reliability for many applications.
