DC-DC Converter

Product Details

The PQ60025ETL35 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 13).

Operational Features

• High efficiencies, 88% at full rated load current
• Delivers up to 35 A of output current with minimal derating
- no heatsink required
• Wide input voltage range: 35V – 75 V, with 100 V 100 ms input voltage transient capability
• Fixed frequency switching provides predictable EMI performance
• No minimum load requirement means no preload resistors required

Mechanical Features

• Industry standard Eighth-brick pin-out configuration
• Standard size: 0.90" x 2.3" (22.9x58.4 mm)
• Total height only 0.320" (8.13mm), permits better airflow and smaller card pitch
• Total weight: 0.85 oz (24 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)
• Remote sense for the output voltage compensates for output distribution drops
• Output voltage trim permits custom voltages and voltage margining

Safety Features

• 2250 V, 30 MW input-to-output isolation
• UL 60950-1 recognized (US & Canada), basic insulation rating
• TUV certified to EN60950-1
• 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 standard
• RoHS compliant (see last page)

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
