Single Output UEP Models  
Ultra-High Density, 2" x 1", 1.2-6 Amp,15-30 Watt DC/DC’s  
FEATURES  
PRODUCT OVERVIEW  
The UEP Series DC/DC Converters deliver  
the most power/current (up to 30W/6Amps)  
from a 1" x 2" package. And because of their  
footprint compatibility, they can be used as  
drop in replacements for their bigger brothers,  
the standard 2" x 2" and 1.6" x 2" devices,  
commonly used in the industry.

Choice of 3 input ranges:  
10-18V, 18-36V, 36-75V

Models Include  
3.3V @ 4.5A or 6A  
5V @ 3.5A or 6A  
15V @ 1.2A  
12V @ 1.4A  
By combining a high-frequency (340kHz),  
high-efficiency (to 89%), synchronous-rectifier  
topology with the newest components and  
time-tested, fully automated, SMT-on-pcb  
construction, these UEP Models are able  
to bring you 15-30W in the standard 2" x 1"  
package from which most competitors can  
only get 5-10W. All UEP’s deliver their full  
output power over ambient temperature  
ranges from –40°C to as high as +70°C  
(model and input voltage dependent) without  
heat sinks or supplemental forced-air cooling.  
Devices derate to +100°C.  
Output voltages are 3.3, 5, 12 or 15 Volts.  
Input voltage ranges are 10-18V (“D12”  
models), 18-36V (“D24” models) or 36-75V  
(“D48”) models. All models feature input pi  
filters, input undervoltage and overvoltage  
lockout, input reverse-polarity protection,  
output overvoltage protection, output current

Standard features also include on/off control  
and output-trim. All models are certified to  
IEC950, UL1950 and EN60950 safety require-  
ments for OPERATIONAL insulation. “D48”  
models (36-75V inputs) are CE marked.  
UEP Series DC/DC’s are packaged  
in low-cost, light-weight, diallyl phthalate  
(UL94V-0 rated) plastic packages with stand-  
offs. EMC compliance is achieved via a low-  
noise design rather than through expensive  
metal shielding.

Floating Outputs  
Since these are isolated DC/DC converters, their outputs are “floating.” Design-

You can, however, use the +Output (pin 4) as ground/return to effectively

Minimum Output Loading Requirements  
3.3 and 5V models employ a synchronous-rectifier design topology. All models  
regulate within spec and are stable under no-load conditions. 12/15V models  
employ a traditional forward, diode-rectification architecture and require 25mA  
loading to achieve their listed regulation specs. Operation under 25mA load  
conditions will not damage the 12/15V devices; however they may not meet all  
listed specifications.

Filtering and Noise Reduction  
All UEP Series DC/DC Converters achieve their rated ripple and noise speci-  
fications with no external input/output capacitors. In critical applications,  
input/output noise may be further reduced by installing external I/O caps.  
Input capacitors should be selected for bulk capacitance, low ESR and high  
rms-ripple-current ratings. Output capacitors should be selected for low ESR  
and appropriate frequency response. All caps should have appropriate voltage  
ratings and be mounted as close to the converters as possible.

Input Fusing  
Certain applications and/or safety agencies may require the installation of  
fuses at the inputs of power conversion components. Fuses should also be  
used if the possibility of sustained, non-current-limited, input-voltage polarity  
reversals exists. For DATEL UEP Series DC/DC Converters, you should use  
slow-blow type fuses with values no greater than the following.

These converters have a trim capability (pin 6) that allows users to adjust the  
output voltage 5ꢀ. Adjustments to the output voltage can be accomplished  
via a trim pot, Figure 2, or a single fixed resistor as shown in Figures 3 and 4.  
A single fixed resistor can increase or decrease the output voltage depend-  
ing on its connection. Fixed resistors should have an absolute TCR less than  
100ppm/°C to minimize sensitivity to changes in temperature.

Input Overvoltage/Undervoltage Shutdown and Start-Up Threshold  
Under normal start-up conditions, devices will not begin to regulate until the  
ramping-up input voltage exceeds the Start-Up Threshold Voltage (35V for  
"D48" models). Once operating, devices will not turn off until the input voltage  
drops below the Undervoltage Shutdown limit (34V for "D48" models). Subse-  
quent re-start will not occur until the input is brought back up to the Start-Up  
Threshold. This built in hysteresis prevents any unstable on/off situations from  
occurring at a single input voltage.  
+INPUT

Input voltages exceeding the input overvoltage shutdown specification listed in  
the Performance/Functional Specifications will cause the device to shutdown. A  
built-in hysteresis of 0.6 to 1.6 Volts for all models will not allow the converter  
to restart until the input voltage is sufficiently reduced.  
Figure 3. Driving the Negative Polarity On/Off Control Pin  
Dynamic control of the remote on/off function is best accomplished with a  
mechanical relay or an open-collector/open-drain drive circuit (optically iso-  
lated if appropriate). The drive circuit should be able to sink appropriate current  
(see Performance Specs) when activated and withstand appropriate voltage  
when deactivated.  
The two 6 Amp models do not feature overvoltage shutdown and withstand  
surges to 100V without shutting down. For custom overvoltage protection,  
contact DATEL.  
Input Reverse-Polarity Protection  
If the input-voltage polarity is accidentally reversed, an internal diode will  
become forward biased and likely draw excessive current from the power  
source. If the source is not current limited (<10A) nor the circuit appropriately  
fused, it could cause permanent damage to the converter.  
Applying an external voltage to pin 3 when no input power is applied to the  
converter can cause permanent damage to the converter.  
Start-Up Time  
The VIN to VOUT start-up time is the interval of time where the input voltage  
crosses the turn-on threshold point, and the fully loaded output voltage enters  
and remains within its specified accuracy band. Actual measured times will  
vary with input source impedance, external input/output capacitance, and load.  
The UEP Series implements a soft start circuit that limits the duty cycle of the  
PWM controller at power up, thereby limiting the Input Inrush current.  
On/Off Control  
The input-side, remote On/Off Control function (pin 3) can be ordered to oper-  
ate with either polarity (negative polarity available for 12 and 15 Volt models  
only). Positive-polarity devices (standard, no part-number suffix) are enabled  
when pin 3 is left open or is pulled high (+13V to VIN applied with respect to  
–Input, pin 2, (see Figure 2). Positive-polarity devices are disabled when pin 3  
is pulled low (0-0.8V with respect to –Input). Negative-polarity devices are off  
when pin 3 is open or pulled high (+2.4V to +10V), and on when pin 3 is pulled  
low (0-0.5V). See Figure 3.  
The On/Off Control to VOUT start-up time assumes the converter has its nominal  
input voltage applied but is turned off via the On/Off Control pin. The specifica-  
tion defines the interval between the time at which the converter is turned on  
and the fully loaded output voltage enters and remains within its specified  
accuracy band. Similar to the VIN to VOUT start-up, the On/Off Control to VOUT  
start-up time is also governed by the internal soft start circuitry and external  
load capacitance.

Current Limiting  
ON/OFF  
When output increases to 120ꢀ to 190ꢀ of the rated output current, the DC/DC  
converter will go into a current limiting mode. In this condition the output  
voltage will decrease proportionately with increases in output current, thereby  
maintaining a somewhat constant power dissipation. This is commonly  
referred to as power limiting. Current limit inception is defined as the point  
where the full-power output voltage falls below the specified tolerance. See  
Performance/Functional Specifications. If the load current being drawn from  
the converter is significant enough, the unit will go into a short circuit condi-  
tion. See “Short Circuit Condition.”

Short Circuit Condition  
Typical Performance Curves  
When a converter is in current limit mode the output voltages will drop as the  
output current demand increases. If the output voltage drops too low, the  
magnetically coupled primary side voltages will also drop, thereby shutting  
down the PWM controller.  
Temperature Derating Curves for UEP-3.3/4500 Output Models  
17.5  
Following a time-out period, the PWM will restart, causing the output voltage to  
begin ramping to its appropriate value. If the short-circuit condition persists,  
another shutdown cycle will be initiated. This on/off cycling is referred to  
as "hiccup" mode. The hiccup cycling reduces the average output current,  
thereby preventing internal temperatures from rising to excessive levels. The  
UEP is capable of enduring an indefinite short circuit output condition.

Thermal Shutdown

These UEP converters are equipped with Thermal Shutdown Circuitry. If envi-  
ronmental conditions cause the internal temperature of the DC/DC converter  
rises above the designed operating temperature (typically 118°C case), a  
precision temperature sensor will power down the unit. When the internal  
temperature decreases below the threshold of the temperature sensor the unit  
will self start.

Output Overvoltage Protection  
Ambient Temperature ( C)  
°
Output voltages are monitored for an overvoltage condition via magnetic  
coupling to the primary side. If the output voltage should rise to a level which  
could be damaging to the load circuitry, the sensing circuitry will power down  
the PWM controller causing the output voltages to decrease. Following a  
time-out period the PWM will restart, causing the output voltages to ramp to  
their appropriate values. If the fault condition persists, and the output voltage  
again climbs to excessive levels, the overvoltage circuitry will initiate another  
shutdown cycle. This on/off cycling is referred to as “hiccup” mode.
