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 flexibility

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

efficiencies. Models are available with either positive or negative on/off control and

independent output voltage adjustment. "I" suffix 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 filtering, 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).
