DC-DC converters are electrical components that convert a DC voltage from one level to another, like stepping up or stepping down, depending on the application. The V48C2M50BN3 DC-DC converter is a programmable, low-noise device used for isolated power supply applications. It provides an adjustable output from 1.25 to 50 volts, at up to 50 watts of output power. The high efficiency of up to 94% also makes the device highly suitable for battery-operated and solar-powered applications.

The individual functions of the V48C2M50BN3 have been designed to meet the requirements of a wide range of applications. A wide input voltage range of 4.75 to 60 VDC allows the device to be operated with a variety of standard (or even non-standard) sources. A high-speed switching frequency of 200kHz ensures low-noise operation and an efficient power delivery. The built-in protection features, such as over-voltage, over-temperature, and short-circuit protection, add reliability and robustness to the system.

The V48C2M50BN3 converter also has a unique feature: it supports the use of an external synchronization signal (up to 20kHz) to enable the user to further reduce switching noise. High-accuracy voltage and current feedback programming can be realized by controlling twice-per-cycle pulse width modulation (PWM). With the help of this PWM, an output voltage and current can be precisely controlled for the best performance.

The working principle of the V48C2M50BN3 is based on the normal flyback topology. The input voltage is first rectified and then passed to an active switch; this switch is used to generate an energy storing inductor current, which flows in the mains transformer. After the switch is closed, the energy stored in the transformer is transferred to the output capacitor, and finally energize the load. The device can automatically adapt the secondary current according to the load current, ensuring a stable output voltage.

The V48C2M50BN3 is an integrated high-performance DC-DC converter, which is suitable for a wide range of applications, such as adjustable voltage power solutions, DC motor drives, medical power supplies, and telecommunications/data converters. The highly efficient operation allows for energy savings, and the low-noise operation ensures the device meets the requirements of most noise sensitivities. It is also highly beneficial for battery powered applications such as solar power systems, as it reduces the total energy losses. In addition, the built-in protection features make the device highly reliable and robust.
