UWE-100-120W Series Wide Input, Isolated Eighth-Brick DC-DC Converters Input Source Impedance TECHNICAL NOTES UWE converters must be driven from a low ac-impedance input source.

For optimum performance, compo- fuses at the inputs of power conversion components. Fuses should also be nents should be mounted close to the DC-DC converter. If the application used if the possibility of sustained, non-current-limited, input-voltage polarity has a high source impedance, low VIN models can benefit from increased reversals exist. For MPS UWE DC-DC Converters, you should use fast-blow type external input capacitance. fuses, installed in the ungrounded input supply line. Refer to the specifications I/O Filtering, Input Ripple Current, and Output Noise for fuse values. All models in the UWE Converters are tested/specified for input reflected ripple All relevant national and international safety standards and regulations must current and output noise using the specified external input/output components/ be observed by the installer. For system safety agency approvals, the convert- circuits and layout as shown in the following two figures. ers must be installed in compliance with the requirements of the end-use safety standard, e.g., IEC/EN/UL60950-1. External input capacitors (CIN in Figure 3) serve primarily as energy-storage elements, minimizing line voltage variations caused by transient IR drops in Fuse conductors from backplane to the DC-DC. Input caps should be selected for bulk +VIN +VIN +VO capacitance (at appropriate frequencies), low ESR, and high rms-ripple-current ratings. The switching nature of DC-DC converters requires that dc voltage sources have low ac impedance as highly inductive source impedance can affect RLOAD system stability. In Figure 3, CBUS and LBUS simulate a typical dc voltage bus. Your specific system configuration may necessitate additional considerations. –VIN –VIN –VO In critical applications, output ripple/noise (also referred to as periodic and random deviations or PARD) may be reduced below specified limits using filter- Figure 2. Input Fusing ing techniques, the simplest of which is the installation of additional external output capacitors. These output caps function as true filter elements and Input Undervoltage Shutdown and Start-Up Threshold should be selected for bulk capacitance, low ESR and appropriate frequency Under normal start-up conditions, devices will not begin to regulate until response. All external capacitors should have appropriate voltage and current the ramping-up input voltage exceeds the Start-Up Threshold Voltage.

Temperature operating, devices will not turn off until the input voltage drops below the variations for all relevant parameters should also be taken carefully into Undervoltage Shutdown limit. Subsequent re-start will not occur until the input consideration. 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. The most effective combination of external I/O capacitors will be a function of line voltage and source impedance, as well as particular load and layout Start-Up Time conditions. The VIN to VOUT Start-Up Time is the interval of time between the point at which the ramping input voltage crosses the Start-Up Threshold and the fully loaded TO output voltage enters and remains within its specified accuracy band. Actual OSCILLOSCOPE CURRENT measured times will vary with input source impedance, external input/output PROBE +VIN capacitance, and load. The UWE Series implements a soft start circuit that LBUS limits the duty cycle of its PWM controller at power up, thereby limiting the + input inrush current. VIN CBUS CIN – 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 –VIN specification defines the interval between the point at which the converter is CIN = 33µF, ESR < 700mΩ @ 100kHz turned on and the fully loaded output voltage enters and remains within its CBUS = 220µF, ESR < 100mΩ @ 100kHz specified accuracy band. Similar to the VIN to VOUT start-up, the On/Off Control LBUS = 12µH to VOUT start-up time is also governed by the internal soft start circuitry and Figure 3. Measuring Input Ripple Current external load capacitance. The difference in start up time from VIN to VOUT and from On/Off Control to VOUT is therefore insignificant. www.murata-ps.com/support MDC_UWE-100-120W.C06 Page 30 of 35

UWE-100-120W Series Wide Input, Isolated Eighth-Brick DC-DC Converters Short Circuit Condition +SENSE When a converter is in current-limit mode, the output voltage will drop as the output current demand increases. If the output voltage drops too low, the +VOUT magnetically coupled voltage used to develop primary side voltages will also drop, thereby shutting down the PWM controller. Following a time-out period, C1 C2 SCOPE RLOAD the PWM will restart causing the output voltages to begin ramping to their appropriate values. If the short-circuit condition persists, another shutdown –VOUT cycle will be initiated. This on/off cycling is referred to as "hiccup" mode. The –SENSE hiccup cycling reduces the average output current, thereby preventing internal temperatures from rising to excessive levels.

When the internal temperature decreases below the + Vcc threshold of the temperature sensor, the unit will self start. See Performance/ ON/OFF CONTROL Functional Specifications. CONTROL Output Overvoltage Protection UWE output voltages are monitored for an overvoltage condition via magnetic feedback. The signal is coupled to the primary side and if the output voltage rises to a level which could be damaging to the load, the sensing circuitry will power down the PWM controller causing the output voltages to decrease. Fol- -VIN lowing 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 Figure 5.

Trimming Output Voltage Current Limiting UWE converters have a trim capability that allows users to adjust the output As soon as the output current increases to substantially above its rated value, voltages. Adjustments to the output voltages can be accomplished via a trim pot the DC-DC converter will go into a current-limiting mode.

UWE-100-120W Series Wide Input, Isolated Eighth-Brick DC-DC Converters Vertical Wind Tunnel Murata Power Solutions employs a computer controlled custom-designed closed loop vertical wind tunnel, infrared video camera system, and test instrumentation for accurate airfl ow and temperature distribution measurements of power IR Transparent products. The system includes a precision low fl ow-rate optical window Variable anemometer, variable speed fan, power supply input and Unit under speed fan load controls, temperature gauges, and adjustable heating test (UUT) element. IR Video The IR camera monitors the thermal performance of the Camera Unit Under Test (UUT) under static steady-state conditions. A special optical port is used which is transparent to infrared wavelengths. Both through-hole and surface mount converters are soldered down to a 10" x 10" host carrier board for realistic Heating heat absorption and spreading. Both longitudinal and trans- element verse airfl ow studies are possible by rotation of this carrier Precision low-rate board since there are often signifi cant differences in the heat anemometer dissipation in the two airfl ow directions. The combination of 3” below UUT adjustable airfl ow, adjustable ambient heat, and adjustable Input/Output currents and voltages mean that a very wide range of measurement conditions can be studied. Ambient The collimator reduces the amount of turbulence adjacent temperature to the UUT by minimizing airfl ow turbulence. Such turbu- sensor lence infl uences the effective heat transfer characteristics and gives false readings. Excess turbulence removes more Airflow heat from some surfaces and less heat from others, possibly collimator causing uneven overheating. Both sides of the UUT are studied since there are different ther- mal gradients on each side. The adjustable heating element and fan, built-in temperature gauges, and no-contact IR camera mean that power Figure 11. Vertical Wind Tunnel supplies are tested in real-world conditions.
