DC-DC Converter
The SQ60120HZx50 bus 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. The SQ
BusQor® series provides an isolated step down voltage
from 48V to a semi-regulated 12V intermediate bus.
BusQor converters are ideal for customers who need
multiple outputs and wish to build or buy point of load
converters to work with a 12V rail. RoHS Compliant
(see last page).
Operational Features
• High efficiency, 95% at full rated load current
• Delivers up to 50A of output current (600W) with optional baseplate
configuration
• Output droop characteristic allows direct parallel operation
• Operating input voltage range: 35-75Vdc
• Fixed frequency switching provides predictable EMI
• No minimum load requirement
Mechanical Features
• Industry standard pin-out configuration
• Standard Size Open Frame:2.3" x 2.4" (58.4 x 61mm)
• Total Open Frame height only 0.413” (10.49mm),
permits better airflow and smaller card pitch
• Open Frame Weight: 2.6 oz. (75g)
• Flanged pins designed to permit surface mount soldering
(avoid wave solder) using FPiP technique
Safety Features
• UL 60950-1/R2011-12
• EN60950-1/A2:2013
• CAN/CSA-C22.2 No. 60950-1/A1:2011
SQ60120HZx50 Model
Control Features
• On/Off control referenced to input side (positive and negative logic
options are available)
Protection Features
• Input under-voltage lockout disables converter at low Vin conditions
• Output current limit and short circuit protection protects converter
and load from permanent damage and hazardous conditions
• Active back bias limit provides smooth startup with
external load induced pre-bias
• Thermal shutdown protects from abnormal environmental conditions
