DC/DC Converter

Product Details

The DQ63325QMA04 DualQor™ series is a dual output DC/DC 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 rectification and an innovative construction design to minimize 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 technology, resulting in a more reliable product.

Operational Features

• High efficiency, >85% at full rated load current
• Delivers up to 40 Watts of output power with minimal 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

Mechanical Features

• Industry standard pin-out configuration
• Industry standard size: 1.45” x 2.3” (36.8x58.4mm)
• Total height less than 0.43” (10.9mm), permits better airflow and smaller card pitch
• Total weight: 1.5 oz. (43 g)
• Flanged pins designed to permit surface mount soldering (avoid wave solder) using FPiP technique

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

Safety Features

• 2000V, 30 MΩ 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 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
