37 watt, isolated dc/dc converters v out combinations of 3.3/2.5/1.8/1.5 volts dual output mixed voltage, dlv models features figure 1. simpli ed schematic 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 rec- ti? cation), dlv?s are impressively ef? cient (to 85%) and able to supply their full 13 amps of output current (37w for the 3.3v/2.5v models) up to +60c 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 v out 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 (200sec), and low output ripple/noise (80mvp-p). all devices feature full i/o fault protection including: input overvoltage and undervoltage shutdown, output overvolt- age protection, current limiting, short-circuit protection, and thermal shutdown. all dlv models are qual/halt/emi tested and certi? ed to the operational/func- tional-insulation requirements of ul60950/en60950. 48v in models (75v in max.) carry the ce mark selected models include rohs-5 compliance with the lead exception. two independently regulated outputs: 3.3v @ 6a; 2.5/1.8/1.5 @ 7a 13a/37w total output current/power input voltage ranges: 10-18v, 18-36v or 36-75v standard 2" x 2" package/pinout high ef ciency (to 85%) stable no-load operation independent v out trim pins remote on/off control fully isolated (1500vdc); i/o protected output overvoltage protection thermal shutdown ul60950/en60950 certi ed ce marked ?input pwm controller opto isolation reference & error amp switch control v2 output switch control output return v1 output v1 trim (option) v2 trim +input sync (option) on/off control input undervoltage and overvoltage comparators pwm controller opto isolation reference & error amp ? contact datel. ? v1 is the higher of the two output voltages. ? ?

(note: pin 5 is an option, see ordering information.) adjustments to the output voltages can be accom- plished via a trim pot, figure 2, or a single ? xed resistor as shown in figures 3 and 4. a single ? xed 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. ?25.5 down r t (k ) = 3.3 ? v o 3.48(v o ? 1.577) l n l n ?17.4 down r t (k ) = 2.5 ? v o 2.41(v o ? 1.18) l n l n 2.5 volt trim down ?14.17 down r t (k ) = 1.8 ? v o 1.73(v o ? 0.86) l n l n 1.8 volt trim down 3.3 volt trim down on/off control the primary-side, remote on/off control function (pin 4) can be speci? ed to operate with either positive or negative polarity. positive polarity devices (no suf? x) 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 con? gured such that the on/off control pin will enable/disable only the higher of the two output voltages. contact datel for more information.
