DC-DC converters provide invaluable power solutions when conventional low/high voltage source solutions are either unavailable or unworkable. An example of this type of converter is the RP30-4815DE-HC DC-DC converter from the Ixys Corporation. It is versatile, efficient, and designed for a variety of applications within industry and related areas.

The RP30-4815DE-HC is a thirty Watt single output converter which offers input voltage versatility, spanning from two and a half to nine and a half Volts, and provides output voltage from one and a half to eight Volts. To accommodate many applications, Ixys also offers this converter with fourteen other single output voltages. For applications that require double outputs, Ixys has also released the dual output version of the RP30-4815DE-HC.

The main advantages of the RP30-4815DE-HC are its efficiency and small size. It provides up to 89% efficiency using low ESR ceramic capacitors. Output voltage ripple and noise are lower than on other converters as a result. The RP30-4815DE-HC also measures only 1.5 x 0.9 x 0.4 inches, which makes it ideal for tight spaces, such as medical devices, cellular phones, and miniature electronic equipment.

The RP30-4815DE-HC is a high feature, low cost DC-DC converter designed primarily for industrial applications. It is capable of inrush current limiting, over-voltage and over-temperature protection, and short circuit protection among others. The over-voltage protection puts the converter into a safe state if the output voltage exceeds the specified values. The over-temperature protection shuts down the converter if the temperature of the die reaches a certain threshold. Short circuit protection enables the converter to survive brief 400 Volts outputs or even 20V, 50mA sustained short circuit conditions.

The working principle of the RP30-4815DE-HC is based on the buck converter topology. It uses an enclosed surface mount switch mode voltage regulator consisting of two switching transistors, an inductor, an energy storage capacitor, and a circuit board with resistors and capacitors. A high frequency pulse width modulated signal is generated and changes an internal switch between two states. This switching allows the power stored on the input circuit to flow into the output circuit, thereby converting lower voltage input to the desired output voltage.

The RP30-4815DE-HC DC-DC converter is a highly efficient, high feature, and low cost solution for many industrial applications. It is ideal for use in tight spaces, as it takes up minimal space. Its various features offer added protection and help make sure that the converter can survive various conditions. Its small form factor and adequate output power make this converter an ideal choice for any DC-DC conversion needs.
