Transient Input DC-DC Converter The PQ60012SMx25 PowerQor® Mega sixteenth brick converter is a next-generation, board-mountable, isolated, fixed switching frequency DC/DC converter that uses synchronous rectification to achieve extremely high conversion efficiency. The power dissipated by the converter is so low that a heatsink is not required, which saves cost, weight, height, and application effort. All of the power and control components are mounted to the multi-layer PCB substrate with high-yield surface mount technology. Since the PowerQor converter has no explicit thermal interfaces, it is extremely reliable. RoHS compliant (see page 15). Operational Features • High efficiency, 80% at full rated load current • Delivers up to 30W of output power with minimal derating • Operating input voltage range: 35-75V • Fixed frequency switching provides predictable EMI Protection Features • No minimum load requirement • Input under-voltage lockout • Output current limit and short circuit protection Mechanical Features • Active back bias limit • Industry standard sixteenth-brick pin-out configuration • Output over-voltage protection • Thermal shutdown • Height: .327" (8.3mm) low profile and .397" (10.1mm) standard Control Features • On/Off control referenced to input side (positive and negative logic options are available) Safety Features Pending • Remote sense for the output voltage compensates for output distribution drops • Output voltage trim permits custom voltages and voltage margining • CAN/CSA-C22.2 No. 60950-1:2003 • EN60950-1:2001 • Needle Flame Test (IEC 695-2-2) • IEC 61000-4-2 • RoHS compliant (see last page) SMA & SML Mechanical Drawing . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2 SMC Mechanical Drawing . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 PQ60012SMx25 Electrical Characteristics . . . . . . . . . . . . . . . . . . . . . 4-5 PQ60012SMx25 Standards & Qualification Testing . . . . . . . . . . . . . . . . . 6 PQ60012SMx25 Figures . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7 Application Section . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11-14 Ordering Information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15 www.synqor.com
