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.

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 limiting, and continuous

to meet 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 standoffs. EMC compliance is achieved

via a low-noise design rather than through expensive

metal shielding.

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

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. The most effec-

tive combination of external I/O capacitors will be a function of load and layout

conditions.

These converters have a trim capability (pin 6) that allows users to adjust the

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

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

ON/OFF

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 V^INapplied 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 V^OUTstart-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 V^INto 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 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 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

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.

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.

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.

Soldering Guidelines

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 atmo-

spheric humidity. We strongly recommend a mild pre-bake (100° C. for 30 minutes). Your

production environment may differ; therefore please thoroughly review these guidelines
