Dual Output  
Mixed Voltage, DLV Models  
37 Watt, Isolated DC/DC Converters  
OUT Combinations of 3.3/2.5/1.8/1.5 Volts  
V
Murata’s new DLV Series, dual-output, low-voltage DC/DC’s provide any output  
combination of 3.3V (to 6 Amps) and 2.5/1.8/1.5 (to 7 Amps). Designed with two  
control loops for two independently regulated outputs (both using synchronous rec-  
tification), DLV’s are impressively efficient (to 85%) and able to supply their full 13  
Amps of output current (37W for the 3.3V/2.5V models) up to +60°C ambient with  
no derating (model dependent).  
Housed in standard 2" x 2" x 0.5" plastic packages, DLV’s offer a number of  
functional options (positive or negative polarity on the control pin, addition of second  
VOUT trim pin, etc.) that make them pin compatible with, yet more powerful than,  
virtually all 2" x 2" duals from other leading DC/DC manufacturers.  
Assembled using fully automated, SMT-on-pcb techniques, DLV’s provide  
stable no-load operation, excellent line/load regulation ( 1%), quick step response  
(200µsec), and low output ripple/noise (80mVp-p). All devices feature full I/O fault  
protection including: input overvoltage and undervoltage shutdown, output overvolt-  
age protection, current limiting, short-circuit protection, and thermal shutdown.  
All DLV models are Qual/HALT/EMI tested and certified to the operational/func-  
tional-insulation requirements of UL60950/EN60950. 48VIN models (75VIN max.)  
carry the CE mark Selected models include RoHS-5 compliance with the lead  
exception.

Part Number Suffixes  
Standard DLV DC/DC’s provide a Trim function (Pin 9) for the lower  
of the two output voltages. A Trim pin (Pin 5) for the higher voltage can  
be added by indicating a "T" suffix. An "N" suffix indicates that the On/Off  
Control function incorporates negative polarity logic.

These DLV converters have a trim capability (pins 9 & 5) that allow users  
to independently adjust the output voltages 5ꢀ. (Note: pin 5 is an option,  
see ordering information.) Adjustments to the output voltages can be accom-  
plished via a trim pot, Figure 2, or a single fixed resistor as shown in Figures  
3 and 4. A single fixed resistor can increase or decrease the output voltage  
depending on its connection. Fixed resistors should have absolute TCR's less  
than 100ppm/°C to minimize sensitivity to changes in temperature.

➀ All models are specified with external TBD ceramic output capacitors.  
➁ See Technical Notes/Graphs for details.  
➂ Devices may be order with opposite polarity. See Part Number Suffixes and Technical Notes  
for details.  
A single resistor connected from the Trim pin 9 to +Output (pin 8), see Figure  
3, will decrease the lower output voltage. A resistor connected from Trim pin 9  
to Output Return (pin 7) will increase the lower output voltage. See Figure 4.  
➃ Applying a voltage to On/Off Control (pin 4) when no input power is applied to the converter  
may cause permanent damage.  
➄ Output noise may be further reduced with the installation of additional external output  
capacitors. See Technical Notes.  
Similarly, the higher output voltage can be adjusted using a single resistor  
connected from the Trim (pin 5) to +Output (pin 6) or to Output Return (pin  
7). See Figures 3 and 4.  
➅ On/Off control is designed to be driven with open collector or by appropriate voltage  
levels. Voltages must be referenced to the –Input (pin 2).

DLV Series  
Adaptations  
Several different additional configurations are available on these converters.  
Generally, these are modifications of an existing standard product. In some  
cases, they are designated with an additional 5-digit suffix on the end of the  
root parent standard model number. The actual details of the modifi cation  
are contained in a Specifi cation Control Drawing maintained by Murata and  
tracked using this same 5-digit special number suffi x. These adapted prod-  
ucts are normally built in the same production facilities and to the same qual-  
ity standards as catalog products. Usually, they share the same components.  
Once a modified product has been configured and supplied to a customer, it  
may be available as a “standard” product to other customers, assuming there  
is no proprietary status or other restriction. There may be scheduling and  
minimum order requirements for such products. Contact Murata directly if  
you are interested in your own set of adaptations or modifi cations.  
Currently, the following product is offered for sale:  
DLV-3.3/6-2.5/7-D48TN-30865  
DLV-3.3/6-2.5/7-D48TN-30865-Y (RoHS-5)  
This is a standard DLV-3.3/6-2.5/7-D48TN with a 100 Volt overvoltage  
shutdown.  
RoHS-5 compliance refers to the exclusion of the six hazardous substances  
in the RoHS specification with the excepion of lead. C&D Technologies'  
RoHS-5 products use all the conforming RoHS materials, however our  
solders are Sn63/Pb37.
