PQ60018ETL45PRS

Technical Specification PQ60018ETL45 48Vin Input 1.8Vout Output 45A Current 2250Vdc Isolation Eighth-brick DC/DC Converter The PQ60018ETL45 PowerQor® Tera eighth-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 14). Operational Features • High efficiency, 87% at full rated load current • Delivers up to 45A of output current with minimal derating - no heatsink required • Wide input voltage range: 35-75V, with100V 100ms input voltage transient capability • Fixed frequency switching provides predictable EMI performance • No minimum load requirement - no preload resistors required PQ60018ETL45 Module Protection Features • Input under-voltage lockout disables converter at low input voltage conditions • Output current limit and short circuit protection protects converter and load from permanent damage and consequent hazardous conditions • Active back bias limit prevents damage to converter from external load induced pre-bias • Output over-voltage protection protects load from damaging voltages • Thermal shutdown protects converter from abnormal environmental conditions Mechanical Features • Industry standard eighth-brick pin-out configuration • Open frame size: 0.90” x 2.3” (22.9x58.4mm) • Total height only 0.320” (8.13mm) L-option, permits better airflow and smaller card pitch • Open frame total weight: 0.85oz (24g) • Open f rame u nits h ave f langed p ins d esigned t o permit surface mount soldering (avoid wave solder) u sing F PiP t echnique Safety Features • 2250 V, 30 MΩ input-to-output isolation • Certified to 60950-1 requirements for basic insulation (see Standards and Qualifications page) • RoHS compliant (see Page 14) Control Features • On/Off control referenced to input side (positive and negative logic options are available) • Remote sense for the output voltage compensates for output distribution drops • Output voltage trim permits custom voltages and voltage margining Product # PQ60018ETL45 Phone 1-888-567-9596 Contents Mechanical Drawings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 2-3 PQ60018ETL45 Electrical Characteristics . . . . . . . . . . . . . . . . . . . . . . 4-5 PQ60-ET Family Standards and Qualifications (all output voltages) . . . . 5 PQ60018ETL45 Figures . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 6-9 Application Section . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 10-13 Ordering Information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14 Doc.# 005-2ET618F Rev.

Additional output capacitance will mitigate this startup ripple behavior. For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: support@synqor.com) Note 2: Higher values of isolation capacitance can be added external to the module.
