Product Details

The PQ60280HEA13 PowerQor® Exa converter is an isolated, fixed switching frequency DC/DC converter that uses synchronous rectification and a patented topology to achieve extremely high efficiency and power density. This module is ideally suited to support wireless base station amplifiers and for applications to drive cooling fans used in networking systems, servers and data storage units. The Exa series converters offer industry leading useable output power for any standard “half-brick” module. The 28Vo modules are available in open frame and baseplated versions. RoHS compliant (see page 13).

Operational Features

• Ultra-high efficiency, 94.5% at full rated load current, 94% at half rated load current
• Delivers up to 360 Watts of output power with minimal derating
• Input voltage range: 35V – 75V, with 100V for 100ms input transient capability
• Fixed frequency switching provides predictable EMI performance
• On-board input and output filtering

Mechanical Features

• Industry standard half-brick pin-out configuration
• Industry standard size: 2.3” x 2.4” (58.4 x 61.0mm)
• Total height only 0.43” (10.8mm), baseplated unit only 0.50” (12.7mm)
• Total weight: 2.6 oz. (75 grams), baseplated unit 4.3oz. (123 grams)

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
