Overview

The Q48T30033 DC-DC Converter is a high-performance, through-hole mounted converter that operates within an input range of 36-75 VDC and provides an output of 3.3 VDC at 30A. It boasts a compact industry-standard quarter brick format, pushing boundaries with ultra-high efficiency, exceptional thermal performance, and a remarkably low body profile. This product is purposefully designed for telecommunications applications, where it delivers superior thermal management compared to conventional quarter bricks and matches the performance of half-bricks.

Features and Benefits

Designed with a focus on superior quality and reliability, the converter incorporates 100% surface-mount technologies and advanced electric and thermal circuitry. Key features include:

  • Environmentally Friendly: RoHS compliant with lead-free solder options.
  • High Power Delivery: Capable of delivering up to 30A, with higher current capability at 70°C compared to existing products in its class.
  • Efficiency: Operates at 88% efficiency with a 30A load and 89% at 15A.
  • Size and Weight: Features a low profile at 0.28 inches [7.2mm] and a low weight of 1 oz [28g] typical.
  • Industry Standards: Fits the industry-standard footprint and pinout, ensuring compatibility and easy integration.
  • Certifications: Complies with UL 60950 recognized in the U.S. & Canada, and DEMKO certified per IEC/EN 60950.

Functional Highlights

The Q48T30033 converter has no minimum load requirement, can start up into pre-biased output, and does not require a heat sink. It also offers the following functionality:

  • On-board LC input filter.
  • Fixed-frequency operation for stable performance.
  • Comprehensive protection for the device and connected systems.
  • Remote output sense and an output voltage trim range of +10%/-20%.
  • Reliability backed by an MTBF of 2.6 million hours as per Telcordia TR-332.

Performance Characteristics

Conversions are done smoothly with a 100V input transient withstand capacity for 100ms. The device meets FCC Class B and EN55022 Class B with an external filter and all materials are rated UL94, V-0 for flammability.

Applications
