DC DC Converters

The PH50S48-12 is a DC DC converter designed for small to medium power systems applications. It is an efficient, cost effective and reliable solution for converting DC power while maintaining a stable output voltage and current.

Application Field

The application fields of the PH50S48-12 generally include medical, industrial, networking, and telecommunications. It is especially suitable for applications that require reliable steady voltage or current, such as system controllers, medical instrumentation, desktops and laptop computers, and portable equipment.

Working Principle

The PH50S48-12 works on a 3-stage topology, where the input voltage is converted to a higher voltage in the first two stages. The output voltage is regulated using a feedback loop that monitors the output voltage and adjusts the duty cycle to maintain the desired voltage level. The output current is controlled by a current-limiting circuit that limits the current output, thereby preventing over-voltage and over-current protection.

The PH50S48-12 is also equipped with a current-doubler circuit that provides higher current levels by doubling the voltage of the output stage. This feature allows for configuration of the output voltage level up to 50V. The current-doubler feature also helps improve the stability of the output voltage and current feedback loop.

The PH50S48-12 also features a wide operating range and high efficiency. It operates from 24V to 55V and can deliver up to 12A of continuous current. It also features an efficient switching solution that is up to 96% efficient at maximum load.

In summary, the PH50S48-12 is an excellent DC DC converter designed for small to medium power system applications. Not only is it able to ensure stable output voltage and current, but also it has wide operating range and high efficiency. It provides a reliable and cost effective solution for converting DC power.
