All models in our new UCP Series meet UL/EN60950 safety requirements, including each European country’s deviations. A CB Test Certificate/Report is available. All models have BASIC insulation; guarantee 1500Vdc isolation; and because they are designed with Class B thermal insulation, satisfy all safety requirements over their full operating temperatures. UCP Models are designed for demanding telecom, datacom and networking applications. Their "semi-synchronous-rectifier" design (400kHz switching) achieves impressive efficiencies (up to 88%). Output voltages are 12 or 15 Volts. Input voltage ranges are 10-18V ("D12" models), 18-36V ("D24" models) or 36-75V ("D48" models). "D48" models meet the Low Voltage Directive (LVD) and carry the CE mark. For high reliability and affordability, DATEL utilizes high-speed automatic assembly to construct the UCP’s proven SMT-on-pcb designs. All models have been rigorously qualified (including a 500-hour life test) and EMC characterized. Devices are housed in metal cases (with non-conductive baseplates) that incorporate threaded inserts for add-on heat sinks and/or pcb mounting. UCP’s feature input pi filters, input undervoltage and overvoltage lockout, output current limiting, short-circuit protection, and thermal shutdown. Additionally, all devices have output trim capability and an on/off control pin that can be ordered with either polarity. We can easily modify standard-product UCP’s to meet your application-specific requirements. +VOUT (5) +VIN (4) 10 SWITCH CONTROL –VOUT (9) 10 –SENSE (8) –VIN (1) PWM CONTROLLER ON/OFF CONTROL (3) +SENSE (6) UVLO & OVLO COMPARATORS OPTO ISOLATION REFERENCE & ERROR AMP TRIM (7) ~ The On/Off Control function can be ordered with either positive (standard) or negative polarity. 12V- and 15V-output models have a standard forward architecture in which this FET is replaced with a Schottky diode.

Designers will usually use the –Output (pin 9) as the ground/return of the load circuit. You can, however, use the +Output (pin 5) as ground/return to effectively reverse the output polarity. The On/Off Control pin (pin 3) may be used for remote on/off operation. As shown in Figure 5, the control pin is referenced to the –Input (pin 1) and has an internal pull-up resistor (28.7kΩ, 75kΩ and 100kΩ respectively for D12, D24 and D48 models) to the +Input (pin 4). The standard UCP converter is designed so that it is enabled when the control pin is left open and disabled when the control pin is pulled low (to less than +0.8V relative to –Input). When left open, pin 3 is pulled up to approximately 5V on "D24" models and 8V on "D48" models. Filtering and Noise Reduction All UCP DC/DC Converters achieve their rated ripple and noise specifications using the external input and output capacitors specified in the Performance/ Functional Specifications table. In critical applications, input/output noise may be further reduced by installing additional 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 your particular load and layout conditions. Our Applications Engineers will be happy to recommend potential solutions and can discuss the possibility of our modifying a given device’s internal filtering to meet your specific requirements. Contact our Applications Engineering Group for additional details. 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 UCP DC/DC Converters, you should use slowblow type fuses with values no greater than the following. Dynamic control of the 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 obviously be able to sink approximately 1mA when activated and withstand more than 10 Volts 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. The on/off control function, however, is designed such that the converter can be disabled (pin 3 pulled low) while input power is ramping up and then "released" once the input has stabilized. Under these circumstances, it takes approximately 30ms for the output of the fully loaded DC/DC to ramp up and settle to within rated accuracy. For UCP converters configured with the negative-polarity option on the On/Off Control pin ("N" suffix added to part number), operation is exactly opposite to that described above. 4 VIN Range D12 Models D24 Models D48 Models Fuse Value 7 Amps 6 Amps 3 Amps +INPUT 3 ON/OFF CONTROL Start-Up Threshold and Undervoltage Shutdown 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/Lockout 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 obviously avoids any unstable on/off situations at a single voltage. 1 –INPUT Figure 5. Driving the On/Off Control Pin Start-Up Time The VIN to VOUT start-up time is the interval between the time at which a ramping input voltage crosses the turn-on threshold point and the fullyloaded output voltage enters and remains within its specified accuracy band. Actual measured times will vary with input source impedance, external input capacitance, and the slew rate and final value of the input voltage as it appears to the converter. Input Reverse-Polarity Protection Upon applying a reverse-polarity voltage to the DC/DC converter, an internal diode will be forward biased and draw excessive current from the power source. Therefore, it is required that the input current be limited be either an appropriately rated input fuse or a current limited power source. The On/Off to VOUT start-up time assumes the converter has its nominal input voltage applied but is turned off via the On/Off Control. 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. www.murata-ps.com Technical enquiries email: [email protected], tel: +1 508 339 3000 MDC_UCP40-75W.B02 Page 5 of 7 UCP Models UL/EN Approved "Half-Brick" 40-75 Watt, DC/DC Converters Output Trimming VOUT may be trimmed ±5% via a single trimpot or fixed resistor. As shown in Figure 6, the trimpot should be connected between +Output (pin 5) and –Output (pin 9) with its wiper connected to Trim (pin 7). A trimpot can also be used to determine the value of a single fixed resistor which can be connected between pin 7 (Trim) and pin 5 (+Output) to trim "down" the output voltage, or between pins 7 (Trim) and 9 (–Output) to trim "up" the output voltage, as shown in Figure 7. Fixed resistors should be metal-film types with absolute TCR's less than 100ppm/°C to ensure stability. +OUTPUT 4 +INPUT TRIM If you are using both the external Trim and Sense functions, you must not attempt to force the converter output voltage more than 5% above its initial, "untrimmed" value. When UCP DC/DC Converters are tested for output accuracy during final test, the Sense pins are connected directly to their respective output pins. Unlike most other DC/DC converters, UCP DC/DC's do not have their metal case connected to one of their input pins. The "uncommitted" case is connected to pin 2 which, depending upon your system configuration, should be connected to either +Input (pin 4), –Input (pin 1), –Output (pin 9), or earth ground. www.murata-ps.com LOAD 9 Figure 6.

Trim Connections Using Fixed Resistors +OUTPUT 4 +INPUT 5 +SENSE 6 LOAD 1 –INPUT Case Connection 20k9 5-10 Turns –INPUT –OUTPUT The Sense pins (which the converter output sees as having an effective 10 Ohm line impedance) should be connected across the output voltage at the load and not at the output of the converter. See Figure 8. The Sense pins then function similar to the Trim pin, and they effectively have the same ±5% compensation range. If, for example, the combination of load current and line impedance causes a 5V output to drop to +4.75V at its load (a 5% drop), the sense function will compensate by raising the output voltage at the converter to +5.25V. If the load voltage drops to +4.5V, the sense function will not be able to compensate for the full drop, and other measures (like reducing line impedance) must be taken. 7 1 The Sense Pins Switching DC/DC converters incorporate a feedback loop that continuously monitors the difference between the output voltage and an internal precision reference. In situations in which load currents and/or conductor impedances are relatively high, there may be unacceptable voltage drops between the converter output and its load. The purpose of the Sense pins (pins 6 and 8) is to monitor and feed back the output voltage at the load, rather than at the output of the converter, and to adjust the converter output as necessary to maintain the load voltage at its desired level. 5 8 –SENSE –OUTPUT 9 Figure 8.

Along with the standard 2.3" x 2.4" x 0.5" (HS-CP) heat sink, DATEL has designed a low-profile heat sink for height-restricted applications. This new heat sink (HS-CPLP2) is designed with radiant fins that extend 0.51" beyond either side of the 2.4" dimension of the BCP package. The convenience of this design is that the finned extensions protrude only 0.31" below the top surface of the DC/DC converter, allowing components with a profile height less than 0.2" to be mounted on the pc board below the heat sink. Therefore, while the surface area of the low-profile heat sink measures 2.3" x 3.5", pcb real estate is unaffected.
