Product Details

The BusQor® BQ60120HEx30 Exa series converter is a next-generation, board-mountable, isolated, wide input, regulated, fixed switching frequency DC-DC converter that uses synchronous rectification to achieve extremely high conversion efficiency. The BusQor Exa series provides an isolated step down voltage from 35-75V to 12V with tight output voltage regulation in a standard “half-brick” module and is available in open-frame and baseplated version. BusQor converters are ideal for customers who need multiple outputs and wish to use point of load converters to work with a 12V rail. The BusQor Exa series converters offer industry-leading useable output current for powering intermediate bus architechture systems. RoHS 6/6 compliant (see page last page).

Operational Features

• Ultra-high efficiency, 95% at full rated load current
• Delivers 30A of current at (360W) full power with minimal derating - no heatsink required
• Wide operating input voltage range: 35-75V with 100V 100ms input voltage transient withstand capability
• Fixed frequency switching provides predictable EMI

Mechanical Features

• Industry standard half-brick pin-out configuration
• Size: 2.4” x 2.3” (61.0x58.4mm), height: 0.422” (10.72mm)
• Total open frame weight: 2.6 oz (75g)

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 down to 6.0V permits custom voltages and voltage margining (+5%/-50%)
• Short startup inhibit time
