The DLV (Dual Low Voltage) Series from DATEL provides both digital I/O and
core logic supply voltages from a single 2" x 2" industry-standard pinout, plastic
package. The DLV-3.3/6-2.5/7 provides 3.3V @ 6 Amps and 2.5V @ 7 Amps, the
DLV-3.3/6-1.8/7 provides 3.3V @ 6 Amps and 1.8V @ 7 Amps, and the DLV-2.5/7-
2.5/7 provides 2.5V @ 7 Amps and 1.8V @ 7 Amps. All models are available with
input ranges of 10 to 18V (-D12), 18 to 36V (-D24) or 36 to 75V (-D48).
Plug-in compatibility with a number of converters from other leading manufactur-
ers is possible because DATEL offers these 30 Watt converters with the exibility
to add/remove the sync (pin 3) and higher-voltage trim (pin 5). Each output is
independently regulated with its own control loop to provide ±1.0% line and load
regulation. Fully synchronous output topology allows no load operation and high
ef ciencies. Models are available with either positive or negative on/off control and
independent output voltage adjustment. "I" suf x models offer independent, "higher-
voltage" on/off control for proper power sequencing of core and I/O voltages. Both
outputs are internally synchronized to eliminate asynchronous beat frequencies.
All models include input Pi ltering, input overvoltage and undervoltage shut-
down circuitry, output overvoltage protection, output short-circuit and current limit-
ing protection and thermal shutdown. These devices meet IEC950, UL1950 and
EN6950 safety standards. CB reports are available on request. "-D48" models are
CE marked (meet LVD requirements).

Part Number Suf xes
Standard DLV DC/DCs 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" suf x. A Sync pin can also be added and
is indicated by an "S" suf x. An "N" suf x indicates that the On/Off
Control function incorporates negative polarity logic. An "I" suf x provides
independent on/off control (Pin 4) for the higher output voltage.
No Suf x Pins 3 & 5 not installed, positive polarity On/Off Control
T Suf x Pin 5 added for higher voltage Trim option
S Suf x Pin 3 added for Sync Option
N Suf x Negative polarity On/Off Control
