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.
