RP20-1103.3SFR/P-HC

DC/DC converters are electronic circuits that are used to convert direct current (DC) from one voltage level to another. The RP20-1103.3SFR/P-HC is a specific type of DC/DC converter that uses a line isolated flyback transformer and features a low component count and high efficiency. This makes it an ideal solution for applications requiring low power, high isolation voltage, low quiescent current, and small size. In this article, we’ll take a closer look at the application fields and the working principle of RP20-1103.3SFR/P-HC.

Application Fields

The RP20-1103.3SFR/P-HC converter is most commonly used in industrial, communications,medical, and automotive applications. In all of these applications, the converter is used to step up or step down a DC voltage level. For example, in industrial applications it can be used to convert a 24-volt DC input to a 12-volt DC output.

In addition to voltage conversion, RP20-1103.3SFR/P-HC converters can provide power isolation and surge protection. This allows the converter to protect sensitive electronic components from power spikes and sudden voltage drops. It also helps to reduce system noise and electromagnetic interference (EMI).

The RP20-1103.3SFR/P-HC also features an integrated anti-circuit protection, which helps protect against accidental shorts and overloads. This feature makes it suitable for use in safety-critical applications, where reliable power delivery is a must.

Working Principle

The RP20-1103.3SFR/P-HC operates on the flyback transformer principle. This means that the device stores part of the incoming energy in a storage coil, or “flyback transformer”, and then releases this stored energy as an output voltage. In addition, the device is capable of providing power isolation and surge protection thanks to the line isolation feature. The internal circuitry of the device ensures that the input and output voltages are isolated from each other, resulting in high electrical noise immunity.

The device operates in two modes: PFM (pulse-width modulation) and PWM (pulse-frequency modulation). In the PFM mode, the device pulses the output voltage to adjust the output voltage within specified limits. In the PWM mode, the device adjusts the frequency of the pulses to maintain the output voltage within the specified limits.

The device also provides power with low quiescent current, meaning that it only consumes power when it’s actively converting the voltage. This helps to reduce system power consumption and allows for greater power efficiency.

Overall, the RP20-1103.3SFR/P-HC is a versatile and efficient DC/DC converter that can be used in a variety of applications. Thanks to its low component count and high efficiency, the device provides reliable power conversion and protection while minimizing system noise and power consumption.
