37 Watt, Isolated DC/DC Converters
VOUT Combinations of 3.3/2.5/1.8/1.5 Volts
DATEL’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.

These DLV converters have a trim capability (pins 9 & 5) that allow users
to independently adjust the output voltages ±5%. (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). See Figures 3 and 4.

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 modification
are contained in a Specification Control Drawing maintained by DATEL and
tracked using this same 5-digit special number suffix. 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 DATEL directly if you
are interested in your own set of adaptations or modifications.
Currently, the following product is offered for sale:
