DC-DC converters are essential components in a variety of power-control applications ranging from automotive to aerospace, industrial, consumer, and the Internet of Things (IoT). The R12P12S/R6.4 devices from Mornsun’s Power Care family are high-efficiency, small-size DC-DC converters designed for use in a wide range of applications. They offer an operating input voltage range of 8 to 36VDC, a wide output voltage range of 5 to 15VDC, and a variety of output current ratings.

The R12P12S/R6.4 adopt state-of-the-art, high-frequency pulse width modulation (PWM) control technology to ensure stable, high-efficiency DC-DC conversion through the entire input voltage and load range. It also offers several features which are designed to protect the system from overvoltage, overcurrent, and short-circuit conditions.

The device offers several key performance advantages which make it an ideal choice for a wide range of applications. These include an extremely high maximum efficiency of up to 96%, a high-frequency transition of up to 500 KHz, and exceptionally low ripple and noise. In addition, it has a wide temperature range capability of -40°C to +85°C. It supports various communication protocols, including PMBus, CANbus, and RS485.

The R12P12S/R6.4’s working principle starts with an input voltage, typically 12V or 24V, provided to the power stage of the device via a pair of input capacitors. The power stage of the device then converts the energy from the input voltage into high-frequency pulses of current that are then sent to an inductor. The purpose of the inductor is to store energy in the form of a magnetic field and then convert the energy back into a voltage to provide the desired output.

The output voltage is then regulated using the feedback pin which monitors the output and adjusts the duty cycle of the power stage accordingly. The higher the duty cycle of the power stage, the higher the output voltage. The duty cycle is then adjusted to ensure the output voltage of the device is kept within the specified tolerance.

The R12P12S/R6.4 also features several safety protections which are designed to protect the system from damage caused by faults such as short-circuits, over-voltage, and over-current conditions. It also provides a power-shifting function which protects the system from malfunctioning or accidental turning-on of connected loads with low-power input voltage.

In conclusion, the R12P12S/R6.4 is an efficient, high-performance DC-DC converter that is well suited to a variety of application fields. It combines state-of-the-art, high-frequency PWM control with a wide operating input voltage range of 8 to 36VDC, a wide output voltage range of 5 to 15VDC, and several advanced safety features. As such, it is an ideal choice for applications that require reliable high-efficiency, high-performance power conversion.
