DC DC converters are ideal for applications where the power source and load power requirements are different. The PRM48AT480M400A00, a Point of Load DC DC converter manufactured by TDK-Lambda, is designed to provide a highly regulated dc output from a single input dc power rail at higher load current densities. The PRM48AT480M400A00 is a fully featured dc/dc converter designed for applications requiring the highest efficiency, low heat dissipation and regulated output. It features a 48V input voltage, 480 Watts maximum power output, and a 400 kHz switching frequency. With voltage and current monitoring, temperature and over-current protection, the PRM48AT480M400A00 is both robust and reliable.The PRM48AT480M400A00 is suitable for a wide variety of applications including communications, industrial, test & measurement and medical. Its flexible mounting options make it suitable for a variety of conditions and installation locations.The PRM48AT480M400A00 operates by the pulse width modulation (PWM) DC-DC switching converter principle. This principle has been utilized in many DC-DC converter designs and involves using a series of samples and holds to separate the input and output power sources.In operation, the converter takes in a dc input power rail and produces an output dc power rail. The output is regulated by pulse width modulation at a fixed switching frequency. By appropriately adjusting the pulse width or switching time of the PWM signal, the output voltage can be regulated to the desired level. It is also possible to use the PWM technique to regulate output current to the load.In addition, the PRM48AT480M400A00 is designed to provide protection for both the converter and load. Over-current sensing is used to provide protection in the case of excessive current draw from the output terminals, thereby preventing damage to the converter and/or the load. The thermal and temperature protection ensures that the converter does not exceed the maximum operating temperature, ensuring reliability and long life operation.Overall, the PRM48AT480M400A00 is a high efficiency, reliable and robust DC-DC converter that is suitable for a variety of applications. Through the use of advanced technology and careful design, it is able to provide regulated dc output from a single input source and is capable of working at higher load current densities.
