DC-DC Converter
The InQor
®
Half-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. Each module is supplied
completely encased to provide protection from the
harsh environments seen in many industrial and
transportation applications.
Operational Features
• High efficiencies, up to 91% at full rated load current
• Delivers full power with minimal derating - no heatsink required
• Operating input voltage range: 34 - 135 V
• Fixed frequency switching provides predictable EMI
• No minimum load requirement
Mechanical Features
• Industry standard Half-brick pin-out configuration
• Standard size: 2.390" x 2.490" x 0.512" (60.6 x 63.1 x 13.0 mm)
• Total weight: 5oz (142g)
Protection Features
• Input under-voltage lockout
• Output current limit and short circuit protection
• Active back bias limit
• Thermal shutdown
Control Features
• On/Off control referenced to input side
• Remote sense for the output voltage
• Output voltage trim range of -20%, +10%
