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: 35-75Vwith 100V 100ms
input voltage transient withstand capability
• Fixed frequency switching provides predictable EMI
BQ60120HEx30 Model
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
Protection Features
• Input under-voltage lockout
• Output current limit and short circuit protection
• Output over-voltage protection
• Thermal shutdown
• Backdrive protection prevents excessive negative current flow
