PRODUCT OVERVIEW
Measuring just 0.89 × 2.22 × 0.36 inches (22.6
× 56.4 × 9.1mm), these open-frame, low-profile
E-bricks fit the industry-standard quarter-brick
footprint. Now you can “cut-and-paste” the layout
from your last Q-brick design to save time and save
44% board space (1.86 square inches versus 3.3)
in the process.
From a 9-18V, 18-36V or 36-75V input, ULEs
deliver 1.5 to 48 Volt outputs with current up to
20 Amps. They employ an interleaved, synchro-
nous-rectifier topology that exploits 100% of their
duty cycle. They simultaneously achieve high
efficiency, low noise, tight line/load regulation, and
quick step response.
An open-frame design, high efficiency, low-on-
resistance FETs, and planar magnetics embedded
in heavy-copper pc boards all contribute to
impressive thermal derating. The ULEs feature set
includes high isolation (2250Vdc, 48V models),
input pi filters, input undervoltage shutdown,
output overvoltage protection, current limiting,
short-circuit protection, and thermal shutdown. The
standard footprint carries V
out
trim, on/off control,
and sense pins (sense pins are not available on
12V or higher models).
All ULE E-Bricks are certified to the BASIC-
insulation requirements of UL/EN/IEC60950-1,
2nd edition, and all “D48” models (36-75V input
ranges) carry the CE mark. Safety certifications,
EMC compliance testing and qualification testing
are available.
