RP40-1103.3SFR/N-HC

DC-DC Converters posses the ability to transform the output voltage of a direct current (DC) source to the required voltage for a certain application. One such converter is RP40-1103.3SFR/N-HC, which uses a plusenergie flyback converter with a highly efficient switching frequency of 100kHz. In this article, we discuss the application field and working principle of RP40-1103.3SFR/N-HC.

This plusenergie flyback converter has a wide range of applications due to its wide input voltage range from 6V to 28V and wide output voltage range from 0.55V to 6V. Owing to its efficiency of 85.5%, RP40-1103.3SFR/N-HC is ideal for space-limited and power-sensitive systems such as notebook computers, telecom apparatus, handheld instruments and wireless systems. It is also used in low voltage DC-DC applications such as LED lighting.

This converter utilizes its high level of efficiency by employing a zero-voltage switching mechanism at the switching transistor. This mechanism enables each switching device to turn on, even when the input voltage drops below the output voltage, resulting in nearly zero turn-on/off times. This an efficient way of managing electricity.

The converter also features an active ripple control (ARC) topology, wherein the switching voltage reaches the output voltage quickly and the ARC quickly reduces the controller output voltage ripple, achieves low output voltage noise and has the advantage of no additional components such as snubber resistor or capacitor.

RP40-1103.3SFR/N-HC uses a synchronous rectification technique which results in high efficiency and also helps in fast transient response. The converter also has internal protection features such as short circuit protection, over temperature protection, and over current protection to prevent damage to the converter.

In summary, the RP40-1103.3SFR/N-HC is a high efficiency, low-voltage DC-DC converter that can be used for a wide range of applications. It utilizes a plusenergie flyback converter with a highly efficient switching frequency of 100kHz and an active ripple control (ARC) topology. The converter uses a zero-voltage switching mechanism and a synchronous rectification technique to achieve higher efficiency. Lastly, it also has internal protection features to guard against damage.
