Q48T30033 DC-DC Converter Data Sheet

Category: Electronics, Other Semiconductors, Powerone

Overview

The Q48T30033 is a quarter brick, through-hole mounted DC-DC converter designed for telecommunications and other applications, offering a combination of high performance, efficiency, and reliability. The product is notable for its low profile, high current output, lack of requirement for a heat sink, and compliance with regulatory standards.

Features

High Current and Efficiency: The converter delivers up to 30A of current and demonstrates high efficiency (88% at 30A load and 89% at 15A load). It operates at a higher current capability at 70°C compared to existing quarter and half brick converters.

Startup and Load: It can start up into a pre-biased output without any minimum load required.

Physical Characteristics: With a low profile of 0.28 inches (7.2 mm) and light weight of 1 oz (28 g), it conforms to an industry-standard footprint of 1.45″ x 2.30″.

Environmental and Safety Compliance: The converter meets the basic insulation requirements of EN60950, withstands 100V input transients for 100ms, and all materials used meet the UL94, V-0 flammability rating. RoHS compliant versions are available, ensuring adherence to environmental standards.

Protection and Regulation: It includes an onboard LC input filter, fixed-frequency operation, with full protections built-in. The output voltage can be trimmed within a +10%/ -20% range using the industry-standard equations, and remote output sense is available for precise voltage regulation.

Reliability: The Q48T30033 promises high reliability with a Mean Time Between Failures (MTBF) of 2.6 million hours, per Telcordia TR-332

Applications

The converter is relevant for diverse applications including telecommunications, data communications, wireless networking, and servers. Its robust design and efficient operation make it suitable for systems requiring a reliable power conversion solution with high current output capabilities.

Certifications and Standards

The device is UL 60950 recognized in the US and Canada, DEMKO certified per IEC/EN 60950, and complies with FCC Class B and EN55022 Class B emissions requirements with an external filter
