R2S-123.3/P

DC DC converters, such as the R2S-123.3/P, are electronic components with a variety of applications. They are typically employed in many electronic systems, such as power supplies, inverters, and motor drives. Unlike linear voltage regulators, DC DC converters change the voltage level of a given power supply without requiring heat sinks. As such, they enable more efficient power conversion.

The R2S-123.3/P is a DC DC converter with a 150mA maximum current rated output. It can operate under an input voltage range of 4.5V to 28V and has an output voltage range of 0.8V to 14V. The R2S-123.3/P features an I/O ratio of 1:175, ensuring the widest possible range of input and output voltages. The device is also extremely small, measuring only 12mm by 9mm by 4.5mm, making it ideal for installation in limited space.

The working principle of the R2S-123.3/P is based on a switched-mode power conversion technique. The application field of this device is typically the PoE (Power over Ethernet) and PoE+ compatible systems. The converter takes advantage of the response time of the switching semiconductors to regulate the output voltage, ensuring that the output voltage remains constant regardless of the load or input voltage changes. The switching frequency of the device is typically set between 200kHz and 4MHz, depending on the application, to minimize RFI (Radio Frequency Interference) emission.

The efficiency of the R2S-123.3/P is excellent, with a typical efficiency of 91%. The device is also highly reliable, with a maximum operating temperature of 85°C and an MTBF (mean time between failure) of over 9 million hours. Additionally, the device offers protection against output voltage over-current, over-voltage, under-voltage, and over-temperature.

In summary, the R2S-123.3/P is a DC DC converter featuring a wide range of applications, a maximum current of 150mA, a switching frequency up to 4MHz, excellent efficiency, and high reliability. It can be used in PoE and PoE+ compatible systems and ensures a stable output voltage through a switched-mode power conversion technique.
