Features
High-Density, 2" x 2"
3.3/5VOUT, 26-40 Watt DC/DC's
Figure 1. Simplied Schematic
Design advancements coupled with state-of-the-art components now allows
DATEL's UWR A-Series to deliver 40 Watts of power in a 2" x 2" package. The UWR
26-40 Watt A-Series DC/DC converters provides up to 9 Amps @ 3.3VOUT and up to
8 Amps @ 5VOUT from input ranges of 10-18V (D12 models), 18-36V (D24 models)
or 36-75V (D48 models).
Designed using an advanced full-synchronous and forward topology, the UWR
A-Series attains efciencies of 90% allowing full power operation to ambient tem-
peratures of +55°C using only natural convection. Built on a time tested, fully auto-
mated, SMT-on-PCB construction, these DC/DC converters provide stable no-load
operation, excellent line (±0.5%) and load (±0.5%) regulation and low ripple/noise
(75mV typical). Models include a full-featured list of fault protection that includes:
input under/over-voltage and output over-voltage protection, output current limiting,
short circuit protection and thermal shutdown.
All models include an On/Off Control function with either positive or negative
logic and output voltage trim adjustment. All models are certied for 1500Vdc
isolation to UL60950 and EN60950 safety requirements. Models that provide input
ranges to 75Vin are CE marked.
INNOVATION and EXCELLENCE
