Overview
The Q48T15050 is a through-hole mounted DC-DC converter that delivers state-of-the-art performance in the quarter brick format with a focus on efficiency, thermal management, and a low-profile design. It is RoHS compliant and designed to work particularly well in telecommunications environments, offering better thermal performance than existing 20A models without the need for heat sinks, due to its optimized circuitry and low-profile packaging.
Features
The Q48T15050 Converter stands out due to its capability to deliver up to 15A of current and its high efficiency, rated at 88% with a 15A load and 87.5% at 7.5A. Built with 100% surface-mount technologies, it touts a robust build for high quality and reliability. It is designed to start up with a pre-biased output without a minimum load requirement, contributes to enhanced cooling by minimizing airflow shadowing, and has a remarkably low profile at 0.28 inches [7.2 mm] and a light weight of 1 oz [28 g] typical.
Standard industry features include a standard footprint of 1.45″ x 2.30″, an industry-standard pinout, and the ability to meet Basic Insulation Requirements of EN60950. The device can withstand input transients of 100 V for 100 ms and includes an on-board LC input filter. This converter also operates at a fixed frequency and offers full protection features, remote output sense, and an output voltage trim range of +10%/−20% using industry-standard equations for trim resistors. The MTBF is rated as high as 2.6 million hours, calculated per Telcordia TR-332.
The Q48T15050 supports both positive and negative logic ON/OFF options and is recognized under UL 60950 in the United States and Canada, as well as DEMKO certified per IEC/EN 60950. In terms of emissions, it meets FCC Class B and EN55022 Class B with an external filter, and all materials meet the UL94, V-0 flammability rating.
Performance Graph and Applications
A performance graph (Fig: 1) is provided, showing available load current versus ambient air temperature and airflow rates for the Q48T15050 converter. It demonstrates the converter’s capacity when mounted vertically, taking into account different airflow rates, ambient temperatures, and ensuring that MOSFET temperature stays below 120°C with an input voltage of 54 V.
Potential applications are suggested for the Q48T15050, including use in telecommunications, data communications, wireless technology, and servers, underscoring the converter’s versatility in a range of high-performance computing and networking environments.
