SQ60120ETA20 Model

Control Features

• On/Off control referenced to input side

• Inherent current share (by droop method) for high current

and parallel applications.

Mechanical Features

• Industry standard eighth-brick pin-out configuration

• Size: 0.90” x 2.3” (22.9x58.4mm), 0.498” (12.65mm)

• Total weight: 1.25 oz (35 g)

The BusQor® SQ60120ETA20 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).
