Narrow Input, Isolated DC/DC Bus Converter
The BusQor™ BQ50120QTA20 bus converter is a
next-generation, board-mountable, isolated, fixed
switching frequency dc/dc converter that uses synchro-
nous rectification to achieve extremely high conversion
efficiency. The power dissipated by the converter is so

Converter
low that a heatsink is not required, which saves cost,
weight, height, and application effort. The BusQor
series provides an isolated step down voltage from 48V
to 12V with no regulation in a standard “quarter-brick”
module. BusQor converters are ideal for customers who
need multiple outputs and wish to design their owDnataSheet4U.com
point of load converters to work with a 12V rail.

NOTES
1) Pins 1-3 are 0.040” (1.02mm) diameter with
0.080” (2.03 mm) diameter standoff shoulders.
2) Pins 4 and 5 are 0.062” (1.57 mm) diameter with
0.100” (2.54 mm) diameter standoff shoulders.
3) Other pin extension lengths available. Recommended pin
length is 0.03” (0.76mm) greater than the PCB thickness.
4) All Pins: Material - Copper Alloy
Finish - Tin/Lead over Nickel plate
5) Undimensioned components are shown for visual
reference only.
6) All dimensions in inches (mm)
Tolerances: x.xx +/-0.02 in. (x.x +/-0.5mm)
x.xxx +/-0.010 in. (x.xx +/-0.25mm)
7) Weight: 1.5 oz. (42 g) typical
8) Workmanship: Meets or exceeds IPC-A-610C Class II
9) UL/TUV standards require a clearance greater than 0.04”
(1.02mm) between input and output for Basic insulation. This
issue should be considered if any copper traces are on the top
side of the user’s board. Note that the ferrite cores are consid-
ered part of the input/primary circuit.
