Overview of Q48T20025 DC/DC Converter
The Q48T20025 is a through-hole mounted DC/DC converter characterized by its industry-standard quarter-brick format. It operates on a 36-75 Vdc input to deliver a 20 A, 2.5 Vdc output. Innovative in design, the Q48T20025 utilizes patent-pending circuit and packaging techniques, which result in its high efficiency, superior thermal performance, and remarkably low-profile body.
Key Features and Benefits
High Power Delivery: Capable of providing up to 20 A current, with better performance at 70°C than many competing 25 A and 30 A models.
High Efficiency: Exhibits an 84.5% efficiency rate at 20 A and 87% efficiency at 10 A without any minimum load requirement.
Compact and Light: Offers the lowest profile in the industry at only 0.28 inches and the lightest weight (approximately 0.88 oz).
Standard Form Factor: Adheres to the industry-standard footprint of 1.45″ x 2.30″ and pinout, ensuring compatibility with a variety of systems.
Reliability and Safety: Comes with Basic Insulation meeting EN60950 standards, a robust 2.6 million hours MTBF calculated per Telcordia TR-332, and materials rated UL94 V-0 for flammability.
Compliance and Certification: Recognized by UL 60950 in the U.S. & Canada, and DEMKO certified per IEC/EN 60950, also meets Class B emissions standards.
Protection and Control Features
Input Transient Tolerance: Can withstand up to 100 V input transient for 100 ms.
Output Regulation: Employs remote output sense for accurate voltage delivery and offers an output voltage trim range of -20%/+10%.
Thermal Performance: Functions without a heatsink and provides protection against over-temperature conditions with auto-restart.
Efficient Start-Up: Capable of starting up into pre-biased outputs and includes ON/OFF control logic options.
Electrical Specifications
The converter’s specifications are provided under standard test conditions of 25°C and 48 Vdc input, with an airflow of 300 LFM. It has an operating input voltage range of 36-75 Vdc and an absolute maximum rating of 80 Vdc continuous.
Its other characteristics include a comprehensive range of isolation parameters, switching frequency set at 435 kHz, and full remote sense compensation. Additionally, it facilitates over-voltage protection and offers an auto-restart feature in case of over-temperature shutdown at PCB level.
The device is fully protected against extreme conditions and is designed for a diverse range of applications, such as telecommunications, data communications, servers, and wireless systems. Furthermore, an onboard LC input filter ensures a clean supply to the device, along with a fixed-frequency operation for consistency in performance.
