Since it is diffi cult to totally characterize TECHNICAL NOTES all applications, some experimentation may be needed. Note that external input Input Fusing capacitors must accept high speed switching currents. Certain applications and/or safety agencies may require fuses at the inputs of Because of the switching nature of DC/DC converters, the input of these power conversion components. Fuses should also be used when there is the converters must be driven from a source with both low AC impedance and possibility of sustained input voltage reversal which is not current-limited. For adequate DC input regulation. Performance will degrade with increasing input greatest safety, we recommend a fast blow fuse installed in the ungrounded inductance. Excessive input inductance may inhibit operation. The DC input input supply line. regulation specifi es that the input voltage, once operating, must never degrade The installer must observe all relevant safety standards and regulations.

After a time-out period, the PWM will automatically attempt to restart, causing the output volt- age to ramp up to its rated value.

An internal bias current causes the open pin to rise to +VIN. Positive-logic devices are disabled ON/OFF when the On/Off is grounded or brought to within a low voltage (see Specifi ca- CONTROL tions) with respect to –VIN. Negative: Models with negative logic are on (enabled) when the On/Off is -VIN grounded or brought to within a low voltage (see Specifi cations) with respect to –VIN. The device is off (disabled) when the On/Off is left open or is pulled high to +13.5VDC Max. with respect to –VIN. Figure 4. Driving the On/Off Control Pin (suggested circuit) Dynamic control of the On/Off function should be able to sink the specifi ed signal current when brought low and withstand specifi ed voltage when brought high. Be aware too that there is a fi nite time in milliseconds (see Specifi cations) between the time of On/Off Control activation and stable, regulated output. This time will vary slightly with output load type and current and input conditions. There are two CAUTIONs for the On/Off Control: CAUTION: While it is possible to control the On/Off with external logic if you carefully observe the voltage levels, the preferred circuit is either an open drain/open collector transistor or a relay (which can thereupon be controlled by logic). The On/Off prefers to be set at approx. +13.5V (open pin) for the ON state, assuming positive logic. CAUTION: Do not apply voltages to the On/Off pin when there is no input power voltage. Otherwise the converter may be permanently damaged. www.murata-ps.com/support MDC_UWQ-12/17-Q48 Series.A07 Page 15 of 17 UWQ-12/17-Q48 Series Wide Input, Isolated DOSA Quarter Brick DC/DC Converters Emissions Performance [3] Conducted Emissions Test Results Murata Power Solutions measures its products for radio frequency emissions [4 [4 [4 [4 [4 [4 [4 [4 [4 [4 [4 [4 [4 [4 [4 [4 [ [4 [4 [4 [4 [4 [4 [4 [4 [4 [4 [ [ [4 [4 [4 [4 [4 [4 [ [ [4 [4 [4 [4 [4 [4 [4 [4 [4 [4 [4 [4 [4 [4 [4 [4] 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] ] La La La La Layout Recommendations yo yo yo yo o o o out ut ut ut R R R Rec ec e ec e ec e e e e e om om om om m m m m m m m mme me m me m me m m m m m nd nd nd nd n nd n n n n n nd d dat at at at at at a a at at at t t t tio iio io io o o o o o o o o o ons ns n ns n n ns n n n n n n against the EN 55022 and CISPR 22 standards.
