technical notes 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 reversal exists. for mps bwr 15-17 watt dc/dc converters, you should use slow-blow type fuses with values no greater than the following: model fuse value all d12a models 4 amp bwr-5/1500-d24a 2 amp bwr-12/725-d24a, bwr-15/575-d24a 2.5 amp all d48a models 1 amp start-up time the v in to v out 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 speci? ed accuracy band. actual measured times will vary with external output capa citance and l oad. the bwr 15-17w series implements a soft start circuit that lim its the duty cycle of the pwm controller at power up, thereby limiting the input inrush current. the on/off control to v out start-up time assumes the converter has its nominal input voltage applied but is turned off via the on/off control pin. the speci? cation de? nes the interval between the time at which the converter is turned on and the fully loaded output voltage enters and remains within its speci? ed accuracy band. similar to the v in to v out start-up, the on/off control to v out start-up time is also governed by the internal soft start circuitry and external load capacitance. 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 (33.5v 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 speci? cation listed in the performance/functional speci? cations 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 suf? ciently reduced. input source impedance the converters must be driven from a low ac-impedance input source. the dc/ dc's performance and stability can be compromised by the use of highly induc- tive source impedances. the input circuit shown in figure 2 is a practical solu- tion that can be used to minimize the effects of inductance in the input traces. for optimum performance, components should be mounted close to the dc/dc converter. if the application has a high source impedance, low v in models can bene? t of increased external input capacitance. i/o filtering, input ripple current, and noise reduction all bwr 15-17w dc/dc converters achieve their rated ripple and noise speci? cations without the use of external input/output capacitors. in critical applications, input/output ripple and noise may be further reduced by installing additional external i/o caps. figure 2. measuring input ripple current c in v in c bus l bus c in = 33f, esr < 700m 7 @ 100khz c bus = 220f, esr < 100m 7 @ 100khz l bus = 12h +input Cinput current probe to oscilloscope + C external input capacitors (c in in figure 2) serve primarily as energy-storage elements, minimizing line voltage variations caused by transient ir drops in conductors from backplane to the dc/dc. input caps should be selected for bulk 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 imped- ance can affect system stability. in figure 2, c bus and l bus simulate a typical dc voltage bus. your speci? c system con? guration may necessitate additional considerations. in critical applications, output ripple/noise (also referred to as periodic and random deviations or pard) may be reduced below speci? ed limits using ? lter- ing techniques, the simplest of which is the installation of additional external output capacitors. these output caps function as true ? lter elements and should be selected for bulk capacitance, low esr and appropriate frequency response. all external capacitors should have appropriate voltage ratings and be located as close to the converter as possible. temperature variations for all relevant parameters should also be taken carefully into consideration. 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 conditions. floating outputs since these are isolated dc/dc converters, their outputs are "? oating," with respect to the input. as such, it is possible to use +output, Coutput or output return as the system ground thereby allowing the ? exibility to generate a variety of output voltage combinations. regulation for bwr 15-17w bipolar converters is monitored between Coutput and +output (as opposed to output to return). minimum loading requirements bwr 15-17w converters employ a classical diode-recti? cation design topology and require a minimum 10% loading to achieve their listed regulation speci? ca- tions and a stable operating condition. load regulation regulation for the bwr 15-17w bipolar converters is monitored between Coutput and +output (as opposed to output to return). as such regulation will assure that voltage between Coutput and +output pins remains within the v out accuracy listed in the performance/functional speci? cations table. technical enquiries email: sales@murata-ps.com, tel: +1 508 339 3000 www.murata-ps.com bwr series 15-17w, dual output dc/dc converters mdc_bwr15-17w.b07 page 4 of 9
on/off control the input-side, remote on/off control function (pin 3) can be ordered to operate with either polarity. positive-polarity devices ("c" suf? x) are enabled when pin 3 is left open (or is pulled high, +13v to v in applied with respect to Cinput, pin 2, see figure 2). positive-polarity devices are disabled when pin 3 is pulled low (0-0.8v with respect to Cinput). negative-polarity devices are off when pin 3 is left open (or pulled high, 3.5v to v in ), and on when pin 3 is pulled low (0-0.5v). see figure 5. 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. 3 2 +vcc 13v circuit 5v circuit Cinput on/off control figure 4. driving the positive polarity on/off control pin figure 5. driving the negative polarity on/off control pin start-up time the v in to v out 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 speci? ed accuracy band. actual measured times will vary with external output capacitance and load. the bwr 15-17w series implements a soft start circuit that limits the duty cycle of the pwm controller at power up, thereby limiting the input inrush current. the on/off control to v out start-up time assumes the converter has its nominal input voltage applied but is turned off via the on/off control pin. the speci? cation de? nes the interval between the time at which the converter is turned on and the fully loaded output voltage enters and remains within its speci? ed accuracy band. similar to the v in to v out start-up, the on/off control to v out start-up time is also governed by the internal soft start circuitry and external load capacitance. if loading from +/C outputs to output return is symmetrical, the voltage at output pins with respect to output return will also be symmetrical. an unbal- ance in loading will consequently result in a degraded v out regulation accuracy from +/C outputs to output return ( Coutput to +output regulation will still be within speci? cation) with a load step from minimum to maximum load and with the other output at full load, the maximum deviation is 2.5% v out nominal. 3 2 +vcc Cinput on/off control 15.5 15.4 15.3 15.2 15.1 15 14.9 14.8 14.7 bwr-15/575-d48a unbalanced output load regulation output load regulation (%) +/C15v out 0 102030 4050 60708090100 +15v @ 0a to 0.575a C15v @ 0.575a C15v @ 0a to 0.575a +15v @ 0.575a current limiting when output current increases to approximately 15% to 50% above 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 dissipa- tion. this is commonly referred to as power limiting. current limit inception is de? ned as the point where the full-power output voltage falls below the speci? ed tolerance. see performance/functional speci? cations. if the load current being drawn from the converter is signi? cant enough, the unit will go into a short circuit condition. see "short circuit condition." 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. following a time-out period, the pwm will restart, causing the output voltages to begin ramping to their appropriate values. 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 bwr 15-17w series is capable of enduring an inde? nite short circuit output condition. thermal shutdown these bwr converters are equipped with thermal shutdown circuitry. if environmental conditions cause the internal temperature of the dc/dc con- verter rises above the designed operating temperature, a precision tempera- ture sensor will power down the unit. when the internal temperature decreases below the threshold of the temperature sensor the unit will self start. figure 4. output voltage accuracy vs. imbalanced loading technical enquiries email: sales@murata-ps.com, tel: +1 508 339 3000 www.murata-ps.com bwr series 15-17w, dual output dc/dc converters mdc_bwr15-17w.b07 page 5 of 9
