Dual Output Mixed Voltage, DLV Models 37 Watt, Isolated DC/DC Converters VOUT Combinations of 3.3/2.5/1.8/1.5 Volts Features Two independently regulated outputs: 3.3V @ 6A; 2.5/1.8/1.5 @ 7A 13A/37W total output current/power Input voltage ranges: 10-18V, 18-36V or 36-75V Standard 2" x 2" package/pinout High efficiency (to 85%) Stable no-load operation Independent VOUT trim pins Remote on/off control Fully isolated (1500Vdc); I/O protected Output overvoltage protection Thermal shutdown UL60950/EN60950 certified CE marked 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 rectification), 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 overvoltage protection, current limiting, short-circuit protection, and thermal shutdown. All DLV models are Qual/HALT/EMI tested and certified to the operational/functional-insulation requirements of UL60950/EN60950. 48VIN models (75VIN max.) carry the CE mark Selected models include RoHS-5 compliance with the lead exception.

(Note: pin 5 is an option, see ordering information.) Adjustments to the output voltages can be accomplished 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. Primary to Secondary Insulation Level Operational 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. 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. 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). ➆ Demonstrated MTBF available on request. ➇ Trim function for the higher of two voltages available with "T" suffix. 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. 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).

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 products are normally built in the same production facilities and to the same quality 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.
