Two independently regulated outputs: 3.3V @ 6A; 2.5/1.8/1.5/1.2V @ 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
DATEL's new DLV Series, dual-output, low-voltage DC/DC's provide any output combination of 3.3V (to 6 Amps) and 2.5/1.8/1.5/1.2V (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

Trimming Output Voltages 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. 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.
Primary to Secondary Insulation Level Operational
All models are specified with external TBD ceramic output capacitors. See Technical Notes/Graphs for details. Devices may be order with opposite polarity. See Part Number Suffixes and Technical Notes for details. Applying a voltage to On/Off Control (pin 4) when no input power is applied to the converter may cause permanent damage. Output noise may be further reduced with the installation of additional external output capacitors. See Technical Notes. 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). Demonstrated MTBF available on request. Trim function for the higher of two voltages available with "T" suffix. See Part Number Suffixes and Technical Notes for details.

On/Off Control The primary-side, remote On/Off Control function (pin 4) can be specified to operate with either positive or negative polarity. Positive polarity devices (no suffix) are enabled when pin 4 is left open or pulled high (+TBDV to +TBDV with respect to Input). Positive polarity devices are disabled when pin 4 is pulled low (0-0.8V with respect to Input). Negative polarity devices are off when pin 4 is high/open and on when pin 2 is pulled low. For applications where power sequencing is critical, the DLV series can be configured such that the On/Off Control pin will enable/disable only the higher of the two output voltages.
