UEP Models

High-Density, 2" x 1"

1-4.5 Amp, 11-18 Watt DC/DC's

The UEP 11-18Watt series DC/DC converter is an alternative pinout for DATEL’s

ﬂagship A-Series. An external pinout conﬁguration affords the design layout to be

oriented for optimal thermal performance thereby increasing available output power

as much as 20%. Available in a 1" x 2" package, these converters can deliver up to

18 Watts at the same ambient temperatures as their 15 Watt counterparts.

By combining a high-frequency (340kHz), high-efﬁciency (to 88%), synchronous-

rectiﬁer topology with the newest components and time-tested, fully automated,

SMT-on-pcb construction, these UEP Models are able to bring you 11-18W 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 fea-

ture input pi ﬁlters, input undervoltage and overvoltage lockout, input reverse-polarity

protection, output overvoltage protection, output current limiting, and continuous

short-circuit protection. Standard features also include On/Off Control and output-

trim. All models are certiﬁed to IEC950, UL60950 and EN60950 safety requirements

for OPERATIONAL insulation. "D48" models (36-75V inputs) are CE marked.

UEP 11-18W 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.

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 volt-

age ratings and be mounted as close to the converters as possible.

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

Start-Up Threshold and Undervoltage Shutdown

Sync Function (Optional)

Under normal start-up conditions, UEP DC/DC Converters will not begin

to regulate properly until the ramping input voltage exceeds the Start-Up

Threshold. Once operating, devices will turn off when the applied voltage

drops below the Undervoltage Shutdown point. Devices will remain off as

long as the undervoltage condition continues. Units will automatically re-start

when the applied voltage is brought back above the Start-Up Threshold. The

hysteresis built into this function avoids an indeterminate on/off condition at

a single input voltage. See Performance/Functional Speciﬁcations table for

actual limits.

Contact DATEL for further information.

Start-Up Time

The V^INto 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 capac-

itance, and load. The UHE 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 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 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 V^INto VOUT start-up, the On/Off

Control to V^OUTstart-up time is also governed by the internal soft start

circuitry and external load capacitance.

The input-side, remote On/Off Control function (pin 4) can be ordered to

operate with either polarity (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 5 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.

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 volt-

age 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 shut-

converter to restart until the input voltage is sufﬁciently reduced.

Figure 2. Driving the Positive Polarity On/Off Control Pin

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.

Current Limiting

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 cur-

rent, 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."

–INPUT

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.

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 voltage used to develop primary side voltages will also

drop, thereby shutting down the PWM controller.

V^IN= 36V-48V (D48)

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 per-

sists, 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

environmental conditions cause the internal temperature of the DC/DC

converter rises above the designed operating temperature, a precision tem-

perature sensor will power down the unit. When the internal temperature

decreases below the threshold of the temperature sensor the unit will self

start. See Performance/Functional Speciﬁcations.

UEP output voltages are monitored for an overvoltage condition via a

comparator which is optically coupled 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 voltages again climb to excessive levels,

the overvoltage circuitry will initiate another shutdown cycle. This on/off

cycling is referred to as "hiccup" mode.
