Murata Power Solutions' 3.6-10W UNR Series consists of non-isolated, 5V-to-1.8V (2A), 5V-to2.5V (2A), 5V-to-3.3V (3A), and 12V-to-3.3V (3A) DC/DC converters in miniature surface-mount and through-hole packages. The "gull-wing" SMT packages (with metal shells and non-conductive plastic baseplates) weigh a mere 17 grams and can withstand lead temperatures up to +230°C. They are compatible with virtually all contemporary pick-and-place and solder-reflow processes. FEATURES  Low cost! High reliability!  1" x 1" through-hole package or 1.01" x 1.01" SMT package  Gull-wing leads; Standard reflow  Complete; No external components  Outputs: 1.8V/2A, 2.5V/2A, 3.3V/3A The true benefits of distributed power will ultimately be realized only when every low-voltage, high-current CPLD, ASIC, DSP, etc. has its own "power plant" right next to it. With isolated DC/ DC converters inevitably residing at the edges of boards in proximity with backplanes and power buses, the "on-board" proliferation of distributed power will continue with more cost-effective, non-isolated devices. The low-cost, easy-to-use (no external components required), highly reliable (100% fully automated SMT construction) 3.6-10W  Inputs: 4.75-5.5V, 10.8-13.6V  Guaranteed efficiencies to 87%  Output noise as low as 40mVp-p  Transient response as quick as 20µsec  –40 to +70°C operation with no derating  On/off control; EMC compliant  IEC950/EN60950/UL1950 approvals  Modifications and customs for OEM's These versatile DC/DC's are fully line and load regulated. They feature user-optional on/off control (for power-sequencing requirements), output current limiting, and short-circuit protection (foldback technique with auto-recovery). Additionally, the 12V-to-3.3V models offer input undervoltage lockout (at 9.6V). Their impressive guaranteed efficiencies enable all models to deliver their fully rated output power from –40 to +65/70°C (ambient) without heat sinking or forced-air cooling. If you've already considered and rejected the use of inefficient, step-down, linear regulators, take a look at one of these new switching buck regulators. Their high efficiency, ease-of-use, longterm reliability, and overall cost effectiveness will impress you.

D12 models have no minimum load requirement. Operating D5 models under no-load conditions will not damage these devices, however they may not meet all listed specifications. The UNR1.8/2-D5 and D5SM require an external 15 pull-up resistor between +Input and On/Off Control for normal operation. See On/Off Control for details. The UNR-3.3/3-D12 and D12SM are specifiied with an external 22µF input capacitor. See I/O Filtering for details. ➁ See Startup Threshold and Undervoltage Shutdown for details. ➂ See On/Off Control for details. ➃ The 22µF external input capacitor required for the UNR-3.3/3-D12 and D12SM should be minimally rated for 1.5Arms ripple current and 125m ESR. Output noise for all models can be further reduced with the installation of external output capacitors. See I/O Filtering for details. ➄ Current limiting initiates at approximately 30% above rated load. Under short-circuit conditions, output current folds back to approximately 150mA and input current drops to approximtely 50mA. Both remain at those levels until the short is removed. ➅ See Start-Up Time for details. ➆ D5/D5SM models may experience start-up problems if voltages greater than 1.0V (for 3.3V models) or 1.2V (for 1.8/2.5V models) are present across the output pins during power-up.

Fuses should also be used if the possibility of sustained, non-current-limited, input-voltage polarity reversals exists.

The UNR-3.3/3-D12 and D12SM models are tested and specified with a single, external 22µF input capacitor (minimally rated for 1.5Arms ripple current and 120m ESR). In critical applications, input/output ripple/noise may be further reduced by installing additional external I/O caps. Input capacitors, which function primarily as energy-storage elements, should be selected for bulk capacitance, low ESR and high rms-ripple-current ratings. Output capacitors, which function more as true filter elements, should be selected for bulk capacitance, low ESR, and appropriate frequency response. All caps should have appropriate voltage ratings and be mounted as close to the converters as possible. Temperature variations for all parameters should obviously be taken into consideration. The most effective combination of external I/O capacitors will be a function of your line voltage and source impedance, as well as 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. Return Current Paths The Input Return, Output Return and Logic Ground are all connected to each other internal to each device. To the extent possible, all load current should be returned through the Output Return (via low-impedance runs) and all input current returned through the Input Return. Any control signals applied to the On/Off Control pin should be referenced to Logic Ground. The internal trace leading to Logic Ground is not designed to carry high current. Devices should never be installed in a manner that results in high current flow through Logic Ground (i.e., the Input/Output Returns should never be left open or attached via high-impedance connections). Under normal start-up conditions, UNR-3.3/3-D12 and D12SM devices will not begin to regulate until the ramping input voltage exceeds the StartUp Threshold Voltage (typically 10.2V). Once operating, devices will not turn off until the input voltage drops below the Undervoltage Shutdown/Lockout limit (typically 9.6V). 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 indeterminate on/off conditions at a single voltage. Start-Up Time For the three D5 models (that do not have an input turn-on threshold), the VIN to VOUT Start-Up Time is the interval between the time a step input is applied to the device and the fully loaded output voltage enters and remains within its specified accuracy band. For the UNR-3.3/3-D12 and D12SM, VIN to VOUT Start-Up Time is the interval between the time at which a rapidly ramping 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 capacitance, and the slew rate and final value of the input voltage as it appears to the converter. The On/Off to VOUT Start-Up Time assumes the converter is turned off via the On/Off Control with the nominal input voltage already applied to the converter. 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. Internal circuit design of the 3.3VOUT models mandates that no voltages greater than 1.0V be present on the output pins at power-up. 1.8VOUT and 2.5VOUT models can not have voltages greater than 1.2V present on their output pins at power-up. Failure to comply may result in start-up problems. www.murata-ps.com/support MDC_UNR 3.6-10W.C01 Page 5 of 8 UNR Series Single Output, Non-Isolated, 1.8/2.5/3.3VOUT 3.6-10W DC/DC Converters SMT Solder Process for SM models On/Off Control The On/Off Control pin may be used for remote on/off operation. UNR 3.6-10W Series converters are designed so that they are enabled when the control pin is pulled high or left open (normal mode) and disabled when the control pin is pulled low (to less than +0.8V relative to Logic Ground). As shown in the figure and table below, each device has an internal pull-up resistor on its On/Off Control pin whose value and voltage vary with model. 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 appropriate current when activated and withstand appropriate voltage when deactivated. Applying an external voltage to the On/Off Control 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 2/3 pulled low) while input power is ramping up and then "released" once the input has stabilized. The time duration between the point at which the converter is released and its fully loaded output voltage settles to within specified accuracy can be found in the Performance/Functional Specifications Table. CAUTION — Avoid Reflow Ovens For the surface-mount "SM" models of the UNR Series, the packages’ gull-wing leads are made of tin-plated (150 microinches) copper. The gull-wing configuration, as opposed to “J” leads, was selected to keep the solder joints out from under the package to minimize both, heat conduction away from the leads (into the encapsulated package) and shadowing effects. "SM" modules do not currently withstand the standard solder-reflow process with its most common temperature profiles. In order to avoid damage to the converter a selective solder process (i.e. hot air gun or a hand soldering method) with the following parameters must therefore be chosen : Pre-heat phase 30-60°C rise/minute to 150°C maximum. Lead temperature 300°C for 10 seconds maximum. As shown in Figure 3, our tests have determined the optimal landing-pad size to be 160 mils by 130 mils (4 x 3.3 mm).
