DC/DC Converters

The versatile DC/DC converters, such as the PXD1512S12, allow for the operation of a device over a wide range of voltages. By connecting two synchronization lines and using fixed, preset transformers, these converters provide cost-effective solutions for operating devices in a variety of conditions and environments.

Field of Application

DC/DC convertors, such as the PXD1512S12, are ideal for utilizing stepped voltages between points in a variety of environments. This type of multilevel switch converter features a high level of performance when operating over wide input ranges, making it a suitable replacement for linear regulators in many applications. Such conversation applications include industrial automation, computer servers, telecommunications, motor drives, batteries, power supply, medical imaging, consumer electronics, and more.

Working Principle

The PXD1512S12 utilizes pulse-width modulated (PWM) switching to ensure reliable performance under all load conditions. The PWM conversion process is accomplished by multiple seeds (aka sub-converters) working in parallel. Each seed consists of an active switch, driven by an input from a control circuit, which acts as a regulator circuit providing a stable output voltage. The primary output voltage fed to the load is a multiple of the seed output voltage, typically 1.2x the seed value. Each bean therefore functions as a converter, providing a cascaded output voltage in multiple increments for load level control. Additionally, each seed can provide different voltage levels for a variety of load requirements. The PWM switching ensures a low ripple which is further reduced by using an LC π-network filter at the output side.The PXD1512S12 is ideal for high power applications because of its high switching frequency of up to 200kHz and a relatively low output voltage level at each step. The high frequency switching ensures the converter is able to provide high-effciency and a wide range of input voltages. In addition the parallel connection of multiple seeds allows for high output frequencies from the load while ensuring low ripple.

Conclusion

The PXD1512S12 is becoming an increasingly popular choice for DC/DC conversion in a wide range of industrial and commercial applications. Its high performance, wide input range, high-efficiency, low rippleand high switching frequencies ensure a reliable and robust power supply to connected appplication. DC/DC convertors such as the PXD1512S12 are ideal for demading applications that require a wide range of input voltages and/or current levels.
