The QM48T50033-NDBP DC-DC Converter is designed for use in power system applications, including those involving consumer, industrial, communications, aerospace, and automotive applications. The integrated DC input and output circuits allow the converter to be used in wide variety of applications, including those requiring an isolated or regulated output voltage. This DC-DC converter provides a voltage regulation of 2% for input voltages up to 48V, as well as a high efficiency of up to 80%. This versatility and high performance make it suitable for use in many applications, particularly those that require low power consumption and long operating life.

The QM48T50033-NDBP DC-DC converter utilizes a dual stage buck topology to convert the input voltage to its desired DC output voltage. In the first stage, the input voltage is regulated, while in the second stage, the output is regulated with a fixed switching frequency. As the input voltage drops, the output voltage is maintained by decreasing the duty cycle. Additionally, the input voltage is further regulated by a differential sensing technique that reduces power input and prevents the output voltage from exceeding its rated value. This two-stage regulation ensures a more consistent output voltage regardless of load variations.

For current limiting, the converter utilizes a constant-frequency current limit circuit that reduces the output current until the set current limit is reached. Additionally, the converter has a soft-start feature that enables the output voltage to be smoothly increased to its desired value, allowing for a seamless system start up. Other features of the converter include over-voltage protection to prevent too high of an output voltage, over-temperature protection to prevent excessive component stress, and short circuit protection to prevent current overloads.

The QM48T50033-NDBP DC-DC converter is an ideal choice for power system applications due to its highly efficient voltage regulation, wide current rating, built-in fault protection, and cost effectiveness. Whether the application calls for a consumer, industrial, communication, aerospace, or automotive application, the product’s versatility allows for the user to customize the output signal to achieve their desired performance. Overall, the QM48T50033-NDBP DC-DC converter adds value and performance enhancements to any power system application.
