1 / 15 page Product # DQ63318QMA04 Phone 1-888-567-9596 Doc.# 005-2DQ638H Rev. A 1/10/03 Page 1 Technical Specification 48Vin 3.3/1.8Vout 40W Quarter Quarter Brick Dual Brick Dual The DQ63318QMA04 DualQor™ series is a dual output converter that uses the industry standard quarter brick package size. The very high efficiency is a result of SynQor’s patented topology that uses synchronous recti- fication and an innovative construction design to mini- mize heat dissipation and allow extremely high power densities. 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 technolo- gy, resulting in a more reliable product. Dual Output, High Efficiency, Isolated DC/DC Converter DQ63318QMA04 Module Mechanical Features • Industry standard pin-out configuration • Industry standard size: 1.45” x 2.3” • Low profile of only 0.43”, permits better airflow and smaller card pitch • Total weight: 1.5 oz (43 g), lower mass reduces vibration and shock problems Safety Features • 2000V, 10 M Ω input-to-output isolation provides input/output ground separation • UL/cUL 60950 recognized (US & Canada), basic insulation rating • TUV certified to EN60950 • Meets 72/23/EEC and 93/68/EEC directives which facilitates CE Marking in user’s end product • Board and plastic components meet UL94V-0 flam- mability requirements Operational Features • High efficiency, 83% at full rated load current • Delivers up to 40 Watts of output power with mini- mal derating - no heatsink required • Wide input voltage range: 35V – 75V, with 100V 100ms input voltage transient withstand • Fixed frequency switching provides predictable EMI performance • No minimum load requirement means no preload resistors required Protection Features • Input under-voltage lockout disables converter at low input voltage conditions • Output current limit and short circuit protection protects converter from excessive load current or short circuits • Output over-voltage protection protects load from damaging voltages • Thermal shutdown protects converter from abnor- mal environmental conditions Control Features • On/Off control referenced to input side (positive and negative logic options are available) • Output voltage trim: +10%/-10%, permits custom voltages and voltage margining Dual Output Dual Output |
