High efficiency @ 12Vout, 92%
The UWE-Q12 series open frame DC-DC converters deliver up to 120 Watts in an industry-standard
“eighth-brick” through-hole package with a Vin range of 9-36Vdc. Standard fixed-output voltages
include 5Vdc, 12Vdc and 24Vdc.
Up to 120 Watts total output power
DOSA 1/8 brick pinout
The extended 4-to-1 input voltage range is ideal for applications that require a battery back-up,
telecom or portable applications. The modules can be configured with an optional baseplate for
cooling in the most demanding applications.
Over Temperature Protection (OTP)
Over Current Protection (OCP)
Over Voltage Protection (OVP)
2250Vdc I/O insulation
The synchronous rectifier design uses the maximum available duty cycle for greatest efficiency and
low power dissipation. These devices deliver low output noise, tight line/load regulation, stable no-
load operation and fast load step response. The modules are designed to meet 2,250Vdc I/O isolation
with a basic insulation system for the greatest application flexibility. On-board Sense terminals
compensate for load line voltage errors at high output currents and Outputs can be trimmed within
10% of nominal voltage.

A wealth of protection features prevents damage to both the converter and outside circuits. Inputs are
protected from under voltage and outputs feature short circuit protection, over current and over
temperature shut down. Overloads automatically recover using the “hiccup” technique upon fault
removal. The UWE-Q12 is certified to standard safety and EMI/RFI approvals. All units meet RoHS-6
hazardous materials compliance.
Operating temperature range -40 to 85°C
(with derating)

Pre-bias startup support
All units are precision assembled in a highly automated facility with ISO-traceable manufacturing
quality standards.
