Technical Specification PQ60033EKx15 48V Input 3.3V Output 15A Current 2000V dc Isolation Eighth-brick DC-DC Converter The PowerQor® Eighth-brick converter series is composed of next-generation, board-mountable, isolated, fixed switching frequency dc-dc converters that use synchronous rectification to achieve extremely high power 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, 88% at full rated load current • Delivers up to 15A of output current with minimum derating - no heatsink required • Wide input voltage range: 35-75V, with 100V, 100ms input voltage transient capability • Fixed frequency switching provides predictable EMI performance • No minimum load requirement means no preload resistors required PQ60033EKA15 Module Control Features • On/Off control referenced to input side (positive and negative logic options are available) Mechanical Features • Industry standard eighth-brick pin-out configuration • Size: 0.90” x 2.3” (22.9x58.4mm) • Low Profile total height only 0.340” (8.64mm), permits better airflow and smaller card pitch • Total weight: 0.85oz (24g) • Flanged pins designed to permit surface mount soldering (avoid wave solder) using FPiP technique" • Remote sense for the output voltage compensates for output distribution drops • Output voltage trim permits custom voltages and voltage margining Safety Features Pending • 2000V, 30MΩ input-to-output isolation provides input/output ground separation • UL 60950-1 recognized (US & Canada), basic insulation rating • TUV certified to EN60950-1 • Board and plastic components meet UL94V-0 flammability requirements 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 Product # PQ60033EKx15 Phone 1-888-567-9596 CONTENTS Mechanical Drawing - Open frame - EKA & EKL (low Profile) . . . . . . . . 2 Mechanical Drawing - Encased . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3 PQ60033EKA15 Electrical Characteristics . . . . . . . . . . . . . . . . . . . . . . 4-5 PQ60033EKx15 Standards & Qualification Testing . . . . . . . . . . . . . . . . 6 PQ60033EKx15 Figures . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7-10 Application Section . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11-14 Ordering Information . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15 Page No. www.synqor.com Doc.# 005-0005111 Rev.
