PRODUCT OVERVIEW

Choice of 3 input ranges:
10-18V, 18-36V, 36-75V
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.
By combining a high-frequency (340kHz), highefficiency (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 limiting, and continuous

Floating Outputs
Since these are isolated DC/DC converters, their outputs are “floating.” Designers will usually use the –Output (pin 5) as the ground/return of the load circuit.
You can, however, use the +Output (pin 4) as ground/return to effectively
reverse the output polarity.
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.

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.

Filtering and Noise Reduction
All UEP Series DC/DC Converters achieve their rated ripple and noise specifications 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. The most effective combination of external I/O capacitors will be a function of load and layout
conditions.

Trimming Output Voltages
These converters have a trim capability (pin 6) that allows users to adjust the
output voltage ±5%. 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 depending on its connection. Fixed resistors should have an absolute TCR less than
100ppm/°C to minimize sensitivity to changes in temperature.
A single resistor connected from the Trim (pin 6) to the +Output (pin 4), see
Figure 3, will decrease the output voltage. A resistor connected from the Trim
(pin 6) to –Output (pin 5) will increase the output voltage.
Trim adjustment greater than 5% can have an adverse effect on the converter's
performance and is not recommended.

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). Subsequent 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 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.
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.
On/Off Control
The input-side, remote On/Off Control function (pin 3) can be ordered to operate 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.

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 isolated if appropriate). The drive circuit should be able to sink appropriate current
(see Performance Specs) when activated and withstand appropriate voltage
when deactivated.
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.
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 specification 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
When output increases to 120% to 190% 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 condition. See “Short Circuit Condition.”

Single Output UEP Models
Ultra-High Density, 2" x 1", 1.2-6 Amp,15-30 Watt DC/DC’s
Short Circuit Condition
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.

Thermal Shutdown
These UEP converters are equipped with Thermal Shutdown Circuitry. If environmental 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.

VIN = 36V-48V (D48)

12.5
Output Power (Watts)
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.

Output Overvoltage Protection
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.
Murata Power Solutions recommends the specifications below when installing these
converters. These specifications vary depending on the solder type. Exceeding these
specifications may cause damage to the product. Be cautious when there is high atmospheric humidity. We strongly recommend a mild pre-bake (100° C. for 30 minutes). Your
production environment may differ; therefore please thoroughly review these guidelines
with your process engineers.
