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 manufactur­ers is possible because DATEL offers these 30 Watt converters with the fl 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
effi ciencies. Models are available with either positive or negative on/off control and
independent output voltage adjustment. "I" suffi 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 fi ltering, input overvoltage and undervoltage shut-
down circuitry, output overvoltage protection, output short-circuit and current limit­ing 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).

Two independently regulated outputs:

3.3V @ 6A, 2.5V @ 7A or 1.8V @7A

Part Number Suffi xes

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" suffi x. A Sync pin can also be added and

is indicated by an "S" suffi x. An "N" suffi x indicates that the On/Off

Control function incorporates negative polarity logic. An "I" suffi x provides

independent on/off control (Pin 4) for the higher output voltage.

No Suffi x Pins 3 & 5 not installed, positive polarity On/Off Control

T Suffi x Pin 5 added for higher voltage Trim option

S Suffi x Pin 3 added for Sync Option

N Suffi x Negative polarity On/Off Control

I Suffi x Pin 4 independent on/off control of Pin 6 output voltage
