Overview of Q24T30020 DC-DC Converter
The Q24T30020 DC-DC converter is a cutting-edge power solution designed for a range of applications, particularly in the telecommunications sector. The converter stands out for its high efficiency, thermal performance, and low profile in a quarter-brick format, making it an efficient choice for various devices requiring DC to DC conversion.
Features and Benefits
The converter can deliver up to 30A of current and showcases superior performance even at elevated temperatures (up to 70°C) when compared to other quarter-brick and 30A half-brick converters. Its efficiency is evaluated at 84.5% at 30A load and 86.5% at 15A, ensuring energy savings. Notably, the device is designed to work without a heat sink and has no minimum load requirement, which simplifies its integration. With a low profile measuring just 0.28 inches (7.2 mm) and a light weight of approximately 1 oz (28 g), the converter has minimal impact on airflow, enhancing cooling for adjacent components.
Technical Specifications and Compliance
The Q24T30020 adheres to industry-standard dimensions and pinout, and offers features such as an on-board LC input filter and fixed-frequency operation. For safety and regulatory compliance, the converter meets the Basic Insulation Requirements of EN60950. Its design also includes full protection, remote output sensing, an output voltage trim range (10% positive and -20% negative), and a trim resistor guided by standard equations.
Constructed using surface-mount technology, this DC-DC converter complies with RoHS lead-free standards and exhibits high reliability, with a mean time between failures (MTBF) of 2.6 million hours as calculated per Telcordia TR-332. Options for both positive or negative logic ON/OFF control enhance its flexibility for various applications.
Certifications for the converter include recognition by UL 60950 in the United States and Canada, DEMKO certification per IEC/EN 60950, and compliance with FCC Class B and EN55022 Class B emissions requirements with an external filter. Materials used in the converter are rated for UL94, V-0 flammability, assuring safety in operation.
